Birds Saturday!

Mixed flock of Vultures at Tensas NWR. The Black Vultures hunt by sight and the Turkey Vultures by scent. Together they make a formidable clean-up crew of large scavengers.

Mixed flock of Vultures at Tensas NWR. The Black Vultures hunt by sight and the Turkey Vultures by scent. Together they make a formidable clean-up crew of large scavengers. They are protected by The Migratory Birds Act of Congress passed in 1918.

For any of us interested in learnining more about birds, this Louisiana Master Naturalists Northeast birds workshop could be just the event!  2018 was declared to be the ‘Year of the Bird’ in commemoration of the law passed in 1918 that protects migratory birds within the USA. I wish all countries would adhere to such sensible legislation. Birds are living treasures.

Thankfully within America it is now illegal to harm any migratory birds and that includes a great many species, including America’s national bird, The Bald Eagle, many of the song-birds, hummingbirds and both species of vulture that we see in Louisiana.

The Turkey Vulture  is believed to have the best sense of smell in the world and also the Black Vulture, that is more of a visual hunter can safely digest putrid flesh that would otherwise spread disease. We have often seen these birds associating with each other at roost and it is interesting that their complementary sensory powers help ensure that carcasses get cleaned up.

Anyway, there is a wonderful variety of birds in northeast Louisiana and winter is a good time to enjoy unobstructed views in the trees. I hope you can join this workshop!

 

Louisiana Master Naturalists - Northeast

All systems are go for the Birds Workshop this Saturday, January 12. Here’s the flyer:

Please print as needed. I won’t repeat everything below, but here are the highlights:

We convene on the LaTech Campus at 9 a.m. for classroom instruction.

Over the lunch hour, we will travel to Lake D’Arbonne Spillway for field work, and if we want to see more birds, we’ll go to nearby Lake D’Arbonne State Park for more birding. It costs $3 to get into the park. Be prepared!

You can register online through PayPal by clicking on the “Certification” tab above then on the PayPal button provided. If you want to pay on site, please come 15 minutes early and please let me know your plan.

And here’s a gorgeous cardinal from the 1st Day Hike at D’Arbonne State Park. He just wouldn’t come out of the thick stuff for me!

Education For Nature Vietnam Reports Massive Ivory and Pangolin Scale Smuggling Bust at Hanoi’s Noi Bai airport, also rescues bears, Hawksbill and Gibbons, and reviews Ten Crucial Action Areas In Fight Against Wildlife and Forest Crime

Education For Nature Vietnam is continuing to work effectively protecting wildlife, in addition to their education work their wildlife crime unit also freed bears and helped rescue an endangered and protected Hawksbill turtle  from a cooking pot and two gibbons that had been cooped up inside tiny wooden cages for a decade. Both of these rescues were thanks to public calling ENV’s toll-free wildlife hotline.

The evil continues — ENV report this October that Vietnamese authorities seized a massive illegal consignment of pangolin scales and ivory from Nigeria at Hanoi’s Noi Bai airport. According to ENV’s news release, almost a ton of contraband represents the illicit slaughter of a great many animals for the profit of organized criminal gangs.

In preparation for an international Illegal Wildlife Trade conference in London ENV have reviewed their progress so far regarding the ten critically important actions against wildlife and forest crime that they formally identified in 2016.

In brief these are:

1. Take down the leaders of criminal networks

2. Eradicate corruption

3. Establish effective legal deterrents

4. Ban rhino horn trade in any form

5. Destroy all stockpiles of confiscated ivory and rhino horn

6. Strictly monitor tiger farms and stop uncontrolled breeding of tigers at zoos and rescue centers

7. Finish the job: End bear farming in Vietnam

8. Strictly control the licensing of commercial wildlife farms and conservation facilities nationwide

9. Hold local authorities responsible for eradicating consumer wildlife crime in their jurisdictions

10. Pull the plug on internet wildlife crime.

You can read how they have been making some significant progress on these actions on their Education For Nature Vietnam website.

 

2. Powerful New Painkiller Discovered in Liverworts

 Anyone who has ever had cause to seek pain relief will be very pleased to hear that a new form of painkiller very similar to that found within Marijuana has been discovered in Liverworts. This is further evidence that it is often the small, ‘boring’ life-forms that prove to be valuable and it is important for us, even for selfish reasons, to best protect ecosystems in their entirety, whenever and whereever we can.

Life In The Leaf Litter

Autumn is here again in the northern hemisphere and I’m celebrating with an exhibition of images on the theme of ‘Life in the leaf litter’.

Scroll down this page to view a choice of images of wildlife down there amongst the fallen leaves! There’s a lot going on down there. Sometimes even the wildlife can’t move stealthily when there’s a crisp bed of dry leaves to be traversed.

I love the textures and the shapes in the leaf litter.

Recently I saw some very fine local crafts jewelry in the form of copper leaf pendants by Louisiana artist, author and Master Naturalist Amy Ouchley for sale at a gallery in Monroe and we were impressed. See the images at the end of the article for more info and her Facebook.

Emily Caldwell’s Wildlife Art Exhibit and Bayou Diversity 2

Author Kelby Ouchley with artist Emily Caldwell at the exhibition of her delightfully whimsical artwork in downtown Monroe.

Bayoudiversity and Bayoudiversity 2 author Kelby Ouchley with artist Emily Caldwell at the exhibition of her delightfully whimsical artwork in downtown Monroe.

Last night Kimmie and I celebrated the much-awaited launch of Kelby Ouchley’s  Bayou Diversity 2 by heading downtown to Monroe’s Central Business District for the Bi-monthly art festival Downtown Gallery Crawl, from 5-9 pm. There , amongst other wonders, we found an exhibition by artist Emily Caldwell of her spirited illustrations of nature that enrich the new sequel to Kelby Ouchley’s original Bayou Diversity, a seminal collection of his writings for radio broadcast celebrating the nature and people of Louisiana, published by LSU Press.

We had enjoyed her artwork in that book and also her mixed media art-work in the exhibition of ‘Wild! Art’ at Union Museum of Art and History in Farmerville last winter. She’s a brilliant artist, capturing the essence of her subjects with a whimsical flourish of their own vivacity juxtaposing natural curvilinear forms with geometric print patterns that seem to emphasize the subjects’ natural forms in contrast with their regularity and in combination project the image. Her lichen covered twig is jaw-dropping — I’ve seen that very twig on the forest floor with its lichen crust. She’s captured it very skillfully.  If you enjoy nature, and particularly art depicting the nature and wildlife of Louisiana check out her website https://emilycaldwell-art.com/

Her artwork for Bayou Diversity 2 is great!

I’m a bit embarrassed to say how much I didn’t know about this Sportsman’s Paradise before reading Bayou Diversity.  In that sense, I think Bayou Diversity is similar to E.O. Wilson’s Diversity of Life; I think both books are literary watersheds, both written by southern gentlemen greatly impressed by the nature of the southern United States and passing on that wonder and their insights to their readers.  This natural world makes a lot more sense having read them.

You should know that there are generations of local natural history knowledge in the Ouchley family, I seriously think that the Bayou Diversity books should be required reading. As should be the children’s book “Swamper: Letters from a Louisiana Swamp Rabbit” by Kelby’s wife Amy. It’s beautifully insightful of southern wildlife in its habitat.

For a foretaste of Kelby’s writings, why not visit www.bayou-diversity.com ?

There’s a lot of knowledge and careful thought invested in these pages, but there’s also inspiration. Can appreciation of nature be transferred? Yes, indeed. I think that that transfer is wholesome and essential. Just as an art teacher can show students how to appreciate the quality of light, and how light reveals form and texture, a good writer and a good artist can distill their informed observations of nature and pass on that exquisite liqueur to be enjoyed in perpetuity for as long as we and the species and phenomena share our common environment.

Furthermore, I dare say that the more people who read this book, then the longer we’ll be around together to make such observations. Ignorance is expensive and opportunity costs are very real.

As the titles suggest, the Bayou Diversity books are intelligent reading matter, biodiversity means the extent of difference (variety) in living organisms and bayous, as Kelby helpfully explains, are the water bodies with seasonally varying degrees of flow and varying shorelines, peculiar to the southeastern United States. Put them together and you have the subject of these books. It is the very rich extent of this biodiversity and its ecological and social interactions that make for fascinating reading and amount to an extraordinarily rich natural heritage of which every American should feel proud.

For foreign nature-lovers such as myself, Kelby’s writing is pure gold but anybody interested in the nature of the southeastern US will find these books enjoyable and mind-expanding.

I have to say that the books are beautifully written too, with the type of witty clarity that I most admire in writers. I’m quite selfish about my reading matter, I expect it to improve my mind and expand my knowledge.

If you don’t know some very fundamental stuff about North American nature, for example that the flapping birds tend to do their migrating at night and the soarers by day, then fear not because enlightenment is at hand.

While the first book covers a wide range of critters and critter behaviour, natural phenomena and human interactions with nature, there’s only so much that can be packed into 225 pages, hence the need for this sequel about 20 yrs later that further expands on the subject by featuring new wildlife, phenomena and historical interactions with nature and by adding to subjects previously covered. I have only just bought it and so haven’t read much of Bayou Diversity 2 yet.

Anyway, like a box of chocolates, these are books that can be enjoyed in various ways — at the run as if a novel, or as reference works, or randomly dipped.  In my family we’ve used the first book in all three ways. The short chapters lend themselves very well to pre-sleep reading — they’ll calm a busy mind and ready it for repose, also suit the limbo of the waiting room and suit reading aloud to others on car journeys. Very often the topics spark interesting conversations and draw out personal observations.

Visitors to Louisiana should read Bayou Diversity books in preparation for their visit and retain for reference; that will add much to the quality of your field experience, I think. It has to mine!

I hope that you enjoy the books as much as my wife and I do.

 

 

 

Wading in to Watershed Dynamics — An Account of LMNNe’s Sixth Workshop.

Dr. Bill Patterson introducing and clarifying key points in his Watershed Dynamics lecture.

As the dominant terrestrial species on this planet we naturally have a rather grounded perspective of our environment; we named our home planet Earth despite the fact that about 70% of its surface is now covered by water.

On Saturday Sept. 15th 2018, 12 members of the Louisiana Master Naturalists Northeast chapter learned more about the crucial relationship between earth and water in a workshop on Watershed Dynamics organized by our Chair, Dr. Bette Kauffman Professor Emeritus of ULM and very capably delivered by Dr. Bill Patterson, as Associate Professor of Forest Soils and Watershed Management at Louisiana Tech University he was the ideal instructor! I learned a lot from the event, facilitated by Bill’s clear and well-articulated presentation and I also greatly enjoyed the fellowship and conversations with these good people.

Professor Patterson explaining the Sparta watershed.

Professor Patterson explaining how the Sparta aquifer (green ) is fed by its watershed (blue).

Shortly before 09.00 we gathered at Louisiana Tech University’s Reese Hall for the sixth workshop event. We met Prof. Patterson unloading a series of boxes of scientific equipment from a sleek minibus and accompanied him to the classroom for a very comprehensive, illustrated presentation and discussion. An excellent introduction to the sbject, If I may say it.

He began with a basic introduction to the concept of a watershed, defining the term as any area of land that drains water into lakes and rivers.

Watersheds are crucially important sources of clean freshwater. We learned about how relatively scarce and precious, clean, fresh, liquid water is on planet Earth, that less than 2.5% of our water is fresh and that of that small subset, 68.7% is locked up in glaciers and pack ice. Very little of the remaining surface water is clean enough to be potable and so groundwater is very, very important. Here in northern Louisiana we are blessed with, and dependent upon the Sparta aquifer — a pressurized body of fresh groundwater which overlays ‘fossil’ saltwater from our marine pre-history.

Dr. Patterson explaing trends in precipitation levels. Climate change is noticeable in various ways, drying in the central portion of the US is gradually spreading eastwards.

Dr. Patterson explaing trends in precipitation levels. Climate change is noticeable in various ways, drying in the central portion of the US is gradually spreading eastwards.

Under normal conditions, our planet’s freshwater is a renewable resource in a constant process of refreshment through the hydrological cycle of precipitation and condensation (fog, rain, sleet, hail and snow) and evapotranspiration which is the return of water back into the atmosphere from atmospheric heating and through plants.

Prof. Patterson systematically introduced the concepts of patterns of orographic and convective precipitation, infiltration and percolation, groundwater, and runoff and streamflow. How storm flow builds, peaks and ebbs, and how land use factors affect watersheds. In order of declining suitability: forests are the best groundcover for watersheds, followed by pasture, then row crops and finally urban development.

We learned that the forest soil to the northwest of the Twin cities, in Webster, Bienville and Winn Parishes with its natural mixture of invertebrate life, bacteria, fungi, underlain with porous sandy soil makes an excellent watershed to feed the Sparta aquifer. Two thirds of our drinking water is organically filtered through forest.

We learned that 15-20 years ago the Twin cities’ industrial and commercial activities used more water than domestic households, but now domestic use exceeds industrial use.

We learned of climate change in terms of more severe weather systems, unpredictable seasonal swings of droughts (like July 5 through October 15th 2016) and increased rainfall (March 13th 2017 21.5 inches in 24 hours) but an overall drying that is spreading eastwards from central Texas and points north. Climate is changing, and it is doing so in unpredictable and complicated ways.  Healthy forests maintain watersheds that improve our overall resilience.

We also learned that withdrawal from Sparta is currently exceeding the natural rate of replenishment and as a result our water table in Monroe has dropped about four feet and is falling at a rate of 1.8 inches per year. So, it’s probably a good idea for households to consider re-using water responsibly and perhaps using more rain water for gardens and possibly greywater in cases where non-food plants need watering.

We discussed the tension between the planners’ need to prevent standing water accumulation in urban areas to control mosquito borne illnesses and the ecological need to retain water in soil rather than just drain it off. Incorporation of swales that create underground lenses of water within the soil seem good.

After a brief coffee break with thanks to Jennifer, the subject turned to description of methods used to measure streamflow and water quality.

I was very interested to see how scientists measure stream flow with a specific formula that can be applied with equal suitability to areas varying from the size of a drainage ditch to the mighty Mississippi! Where Q stands for quantity, V for velocity and A the cross-section area of discharge, then Q = VA.

Water can be studied at culverts, with pre-designed metal chutes (flumes) and even in stream beds by dividing the area into rectangles and triangles with known measurements and combining these distinct areas to ascertain the total area for the formula to be applied. Dr. Patterson showed us instrumentation and sampling equipment including an extendable current meter, an oxygen monitor with thermometer and measuring kits for specific pollutants like nitrates and phosphate.

Water quality factors include the dissolved oxygen, turbidity, temperature, phosphate, nitrate and nitrite, and ammonia. Tests for gender-bending endocrine disruptors or other chemical pollutants are possible, but are more specialist and expensive.

Some of these water quality factors interplay, for example:

  • water temperature and dissolved oxygen levels are related. Cooler water holds more oxygen, warmer water holds less.
  • Nitrates and oxygen are related in the way that excess nitrogen boosts plant growth which booms in algal blooms that then die and rot, consuming available oxygen, reducing dissolved oxygen to dangerously low levels that are lethal to fish and other gilled organisms.
  • Turbidity leads to higher temperatures because the sediment particles absorb more solar radiation than pure water alone can do. Excess sediment can choke fish and invertebrate eggs and block plants’ ability to photosynthesize starch from sunlight and carbon dioxide.

He showed us a Google Map of the Redwine Creek with study stations marked. The lower measuring station in land owned by Weyerhauser that was formerly granted the status of Wildlife Management Area is no longer accessible unfortunately. The creek supplies water to The Dugdemona river which in turn runs into the Red river which feeds the massive Atchafalaya wetlands, a huge wildlife-rich area approximately the size of Wales. An ecological jewel.

We would visit two of the study stations after lunch to sample the water quality and stream life. The first was on Grambling University grounds, accessed from Facilities Road.

Dr. Patterson arranged a Tech van to take us to the stream; some members drove independently. We disembarked at Redwine Creek in Grambling, La. Members helped carry equipment down to the stream.

First, we measured the discharge (streamflow), temperature, turbidity and dissolved oxygen level.  Members with waders gamely waded out to the culverts for sampling, others used dipnets and Dr. Patterson and Kalem Dartez cast a weighted castnet, both had good style! Betty and Suzanne used a seine net in tandem.  Kimmie photographed a fast moving Southern Broad-banded Watersnake.  Nobody fell in, but you can see from the data that we wouldn’t have contracted a cold or pneumonia from the warm water if any of us had taken a dip.

Stats

Redwine Creek North

Turbidity: 74.55 NTU

Dissolved Oxygen: 7.20 DO

Temperature: 27.3°C / 81.14°F

On May 1st 2018 students had recorded the turbidity at 41.8 NTU, temperature as 18.5°C and Dissolved Oxygen as 8.9 so we were able to determine that water conditions had changed with regard to these factors and their quality at this station can be considered impaired. Even so, there was healthy-looking aquatic life in the form of two species of fish, a watersnake and two crawfish.

Afterwards we noted that soil disturbance on the banks would be at least partially responsible for the increased turbidity, it would be good to look into turbidity amelioration on that stretch.

We observed the following wildlife:

We re-boarded the van and visited the second station where the river has passed through a water treatment plant and actually falls in a small cascade over a concrete step just past the bridge. Here the turbidity had dropped by 30.79 NTU. Dr. Patterson also conducted a Phosphate test which showed the level to be impaired.

I am very grateful to everybody who cast their eyes about looking for the rubber eye-cup that fell off my camera’s new LCD panel loupe* near the second station. My thanks to Jeff Barnhill for finding it and getting it back to me.

From the conversations in the minibus it was clear that members enjoyed the event and found it very interesting and stimulating, Kimmie and I certainly did too.

Water is very much a part of life in northeastern Louisiana and we are never far from a water body of some sort. Some of our members live right by the Mississippi, others near Bayou D’Arbonne, and others Cheniere Lake. For our own part, we feel fortunate to have springs from the Sparta aquifer at the bottom of our land near Farmerville and so all of this seemed particularly interesting to us.

This is my first draft of the account, it is likely to be improved by the peer review process, so you can expect some revision.

*A note on LCD Loupes

I think they’re a brilliant accessory. Recently I’ve been aware of missed focus on some of my pictures and I have always had difficulty in bright sunlight seeing details on my cameras’ rear LCDs. I bought an LCD Loupe for about $70 inc. tax postage etc. last week and feel that it has helped a lot! The unit is about 10cm long and has a diopter adjustment ring and a rubber eyecup that you can use for either eye, that hugs your cheek. Watch out that you don’t knock off your eye-cup with the camera strap. It might be worth keeping that in a pocket and just applying it when you’re ready to shoot. It works pretty well without the eye-cup, but this extra friction on the cheek helps stabilize the camera nicely too which means you can knock back that ISO for cleaner images with more detail.

I don’t know about you, but I find any steadying effect is useful in wildlife photography because the more excited I am about my subject, the more likely I am to spoil a picture in borderline conditions through camera shake. How often the great shots are in lower light. What a pain to blur the special opportunities! Or be forced to use a high ISO to ensure a suitably fast shutter speed and appropriate depth of field. My cameras all have image stabilization in the lenses, bodies or both, but the steadier I can hold the camera the better.

The unit works in addition to the quick release plate on my Vivitar tripod, so I can have both on at the same time. You can adjust the placement with the side-knobs and flip up the magnifying optic to put it out of the way if you want to view the LCD screen unmagnified. In short, it’s like having a better viewfinder. OK, so you’ll use your camera battery up faster than if you just use the viewfinder, but that’s a penalty I’m prepared to accept for getting that line of finest focus where I want it, more of the time, very handy with a 50mm F1.4 and with macro lenses.

An LCD Loupe by Sevenoak attached to my Pentax K-1. This attaches to the bottom of the camera by connecting to a screwed-on base-plate. It gives a 3X magnified view of the rear LCD which enables me to check finer focus and other details of the picture more carefully.

ARCAS Annual Report 2017 — progress in difficult environment

Cover image of the ARCAS 2017 annual report with an image of a rescued Barn owl.

Right click on the image above and select ‘save’ option to download the ARCAS annual report 2017 to a folder of your choice.

Today I read the latest ARCAS Annual Report (2017) and was pleasantly surprised by the good news it contained. Central America has a wonderful biodiversity but it is a troubled region with logistical challenges ranging from exploding volcanoes to organised criminal gangs involved in wildlife and forest crime.

ARCAS (asociaciòn de rescate y conservaciòn de vida silvestre) is Guatemala’s leading wildlife rescue and rehabilitation organization with dedicated local staff and local and foreign volunteers and student interns working to help care for wildlife that has been rescued from the domestic and transnational illegal wildlife trade. They are also running a sea turtle conservation program on the Pacific Coast with sea turtle hatcheries and environmental education and volunteer activities.

ARCAS’ effectiveness is very much due to the dedication of their staff and collaborative work with partners in law enforcement, Parks authorities and domestic and foreign donors and volunteers.

Please do read the report for the details of their activities in 2017 which in summary include:

  • the intake of 238 species of wildlife to the ARCAS rescue centers, many of them endangered

    and rare, all of them precious to the ecology,

  • the completion of installations for the rehabilitation of small felines and carnivores, an area removed from humans where they can learn to hunt and adapt to the wild.
  • the improvement of habitats for the pumas and jaguars that cannot be rehabilitated
  • the training of 57 students from twelve North American and European universities in Wildlife Medicine and Conservation in Guatemala courses with ARCAS. See the poster on the right.
  • participation in the Colores project on the Pacific coast, protecting Yellow naped amazon (Amazona auropalliata) parrots as a flagship species to conserve the last remaining wild animals and places on the Pacific coast of Guatemala.
    In 2017 COLORES carried out parrot-monitoring and nest protection, environmental education, and public outreach
    in support of anti-trafficking activities.
  • working together with the San Carlos University, CoNAP, HSI and local NGos, to draft and present animal welfare legislation that was passed by the Guatemalan Congress. The report states that “For the first time, Guatemalans have the legal means to denounce acts of cruelty to animals, not only domestic pets, but also wildlife and livestock.”
  • Together with the newly-formed Animal Welfare Unit of the MAGA and Animal Defenders International, ARCAS is working to transport over 50 circus animals to appropriate sanctuaries in Africa and the US.

     

  • With the support of the International Fund for Animal Welfare (IFAW) and the Disney Conservation Fund, this year ARCAS expanded its installations at the San Lucas office and built new enclosures to hold the increasing numbers of animals that it is receiving there, improving their overall well-being and supporting wildlife trafficking enforcement efforts.

     

  • ARCAS is participating in the project “Forestry management and Protection (FMAP) System for Tackling Illegal Logging” funded by the UK Space Agency (UKSA) International Partnership Programme (IPP).
    ARCAS is to work with Guatemalan partners, including the CoNAP, DIPRoNA, the Public Ministry (MP), the National Forestry Institute (INAB) and the Ministry of Agriculture (MAGA) to:
    – Reduce land crime through increased land use change detection with a higher temporal resolution to provide intelligence to enforcement agencies;
    – Upgrade existing traceability systems through the addition of space-based data and GNSS mobile applications to support better forestry management and tackle illegal activities;
    – Increase the efficiency, impact and scalability of the forestry incentive programs by reducing the costs of surveying, monitoring and land-use verification in the current systems.
    This is delivered by a consortium of international technology companies led by Edinburgh-based Astrosat.

This is an impressive body of work and we wish ARCAS the very best of luck with their endeavours.

ARCAS is always interested in being contacted by potential volunteers and donors, so if you think that you can help, please don’t hesitate to contact Development Director, Colum Muccio
