Supporting Standing Change for Purple-cockaded Woodpecker
Tall Timbers helps the U.S. Fish and Wildlife Service proposed change in standing of the Purple-cockaded Woodpecker from endangered to threatened underneath the Endangered Species Act (ESA). The proposal has garnered a very good little bit of media protection, so we needed to share our ideas on each the great causes for the change, in addition to the necessity to preserve the woodpecker on the ESA as threatened for the a long time wanted to attain restoration.
Understanding Endangered Species Act standing
The standing as endangered vs. threatened underneath the ESA is central to the proposed change. Endangered species are vegetation and animals that face an imminent risk of extinction. Threatened species obtain typically the identical degree of safety as endangered species, and are outlined as species that may very well be endangered within the close to future.
Many biologists believed the Purple-cockaded Woodpecker was heading towards extinction about 30 years in the past. Now populations are enhancing all through the chicken’s vary, growing from about 10,000 people within the early Eighties to over 15,000 people at this time.
This development away from an imminent risk of extinction is nice information and suits with the proposed change in standing, nevertheless it additionally doesn’t imply the numerous different necessary circumstances wanted to recuperate the species and take away it from the ESA have occurred.
A change in standing from endangered to threatened can also present a small quantity of flexibility to develop new administration instruments for the woodpecker. Many present approaches had been created with nice warning and concern for ‘imminent risk of extinction’ and have very proscriptive language. The standing change could present alternatives to check different administration instruments to assist develop and assist woodpecker populations. For instance, translocating nestling woodpeckers may assist to alleviate inbreeding in small populations and be extra environment friendly than present approaches primarily based on translocated juveniles.
Sustaining ESA safety as threatened for a number of a long time will nonetheless present the bigger conservation planning wanted for landscape-scale restoration. It’s good to keep in mind that ESA protections for the woodpecker have been useful in avoiding placement of incompatible land makes use of equivalent to pipelines, toll roads and new residential growth in areas just like the Purple Hills area and Division of Protection properties with substantial woodpecker populations.
Recovering the ecosystem, not simply retaining a species
A key aim of the ESA is to recuperate the ecosystems upon which threatened and endangered species rely, relatively than simply retaining a couple of round, amassing them in zoos, or as DNA samples.

For the Purple-cockaded Woodpecker, this implies managing pine forests for the old-growth circumstances that when typified the longleaf pine ecosystem. One estimate locations the unique acreage of old-growth longleaf pine at greater than 60 million acres. In the present day that remnant space is round 12,000 acres, or about 0.004% of the unique extent. In human phrases, that’s akin to the world inhabitants shrinking down to only these presently dwelling within the Purple Hills area.
The Purple-cockaded Woodpecker wants old-growth circumstances as a result of it’s the solely woodpecker in North America that excavates its nest and roost cavities completely in dwelling pine bushes, previous ones. A possible cavity tree must be 70-90 years previous simply to have the best circumstances for excavation, however many choose even older bushes round 150-200 years of age.
The optimistic development in recent times for the woodpecker shouldn’t be from the sudden look of old-growth circumstances. It’s due to the set up of synthetic woodpecker cavities. A biologist with a chainsaw can set up a man-made cavity in about 45 minutes in bushes solely 60-70 years previous. In the present day, synthetic cavities make up the vast majority of cavity bushes obtainable to woodpeckers on many websites. The sponsored housing has helped to maintain woodpeckers on the panorama, however reestablishing old-growth circumstances is finally wanted for the woodpecker to outlive by itself and be faraway from the ESA.
Planning for old-growth and restoration
Tall Timbers is working with a number of state companies to plan for reaching old-growth circumstances on state forests, wildlife administration areas, and parks. The work is in a really early stage with Tall Timbers gathering background data on earlier packages and internet hosting a gathering in April 2022 to start out the method rolling. Our hope is that this kind of planning for old-growth can finally function a mannequin for bringing again old-growth circumstances all through the previous vary of the longleaf pine ecosystem. Restoring old-growth circumstances received’t occur rapidly, however there are areas the place they could be reached inside 50 years.
This work furthers Tall Timbers’ bigger aim of sustaining uncommon wildlife and biodiversity related to fire-maintained ecosystems within the Southeast.
