H is for Herps

I had to type that one carefully for this day 8 entry into the AtoZ Challenge.   One extra letter or wrong letter and I am either attracting the “wrong” crowd or some foodie will wander in here wondering what kind of weird recipes I am promoting here.   Herps is the vernacular for reptiles and amphibians, derived from the general word for them of herpetofauna or their study herpetology.

Herps are dire warning indicators of changes happening around the planet.  Being extremely sensitive indicators of their environment conditions, their extinction rate is skyrocketing.   The IUCN predicts for every four species of herps, one of them is nearing extinction or vulnerable to extinction.   And, it’s accelarating.

The sad bit, 99 percent of the current threatened species are at risk from human activities, primarily those driving habitat loss, introduction of exotic species, wildlife trafficking and climate change.   As far as Endangered Species Act protection, there is very little.  In 2012, there were only 58 of the 1400 species in the ESA that were herpetofauna.

The rates of extinction are quite alarming.   Of course, extinction has happened througout the Earth’s history, long before we were around to screw things up.  Scientists measure the difference between the current rate, and the background extinction rate, or normal rate.   Amphibians, being the most sensitive, the rate may range from 25,039 to 45,474 times the background extinction rate, according to a study by Malcum McCallum in the Journal of Herpetology in 2007.

The best thing people can do is educate themselves on the state of herps in their area, do not buy herps as pets (!), be wary of chemicals we use around our house and on our local landscape, and reduce our carbon footprint.  And, if you come down with a case of herps, be thankful!

Some great resources in Michigan are:

The Fusion Series is a pairing of my fondness for playing with multiple exposures with the aspects of connectivity in nature. With spring wildflower season well underway, it is important to remember a wildflower doesn't exist in isolation. It is a product of the soil...

In honor of 2022-02-22 or 22-02-2022 but certainly not the bizarre order of 02-22-2022 (apparently we Americans don't do metric and we can't get our dates in a logical order like the rest of the world), published at 22:22 ET - here are some photographs celebrating the...

My mind is and has been, toying with a concept for quite a long time now. It is difficult to put in words, let alone imagery. It is the concept of the dynamic dichotomy that exists around us with destruction vs. protection, life vs. death, forest vs. trees, assembly...

    Not only are they disappearing, they’re mutating as well. A photographer friend of mine documents frogs and other herps that have extra legs or some other deformity. They’re seeing more and more of it.

    This is one subject that I haven’t filmed a lot of and there’s really no excuse why. I have some wetlands near the tallgrass prairie I’ve been documenting so I really need to get some waders on and get in the water!

    I love these photos! Very nicely done. I hope with nice images of these animals we can help a couple more people think about these animals prior to destroying their habitats.
