Why woodpeckers are endangered

There are also 1, known active clusters on private lands in 11 states and the existence of up to additional groups is considered likely -- of these groups are protected, in agreements involving private landowners [1]. Most important for the recovery of red-cockaded woodpeckers is the widespread and frequent application of early-mid growing season fire and the preservation of large, older longleaf pine trees [1]. Two types of catastrophes pose threats to red-cockaded woodpecker populations: catastrophic winds hurricanes, downbursts and tornadoes and outbreaks of southern pine beetles [1].

Although beetles typically do not pose a major threat, hurricanes have caused extensive damage to red-cockaded woodpecker populations for example, Hurricane Hugo in [1]. In order to protect the species from this threat, a number of populations, broadly spaced geographically and including many inland populations, need to be maintained [1].

The U. Fish and Wildlife Service formulated recovery criteria for the red-cockaded woodpecker by creating 11 recovery units delineated according to eco-regions [1]. These populations are distributed among recovery units to ensure the representation of broad geographic and genetic variation, and goals have been set for total numbers of active clusters at each location [1]. The hope is to achieve species viability by maintaining a number of populations within each unit that, with immigration, are able to withstand genetic and demographic threats [1].

Fish and Wildlife Service estimates that if all recovery recommendations were followed, the red-cockaded woodpecker could be considered for downlisting by and delisting by [1]. Fish and Wildlife Service. Recovery plan for the red-cockaded woodpecker Picoides borealis : second revision. Atlanta, GA. Conner, and J. A leading figure in the hunt for the ivory-billed woodpecker said it was premature to call off the effort, after millions of dollars spent on searches and habitat preservation efforts.

Hilton-Taylor said there can be unintended but damaging consequences if extinction is declared prematurely. They said the 23 extinction declarations were driven by a desire to clear a backlog of recommended status changes for species that had not been acted upon for years. They said it would free up resources for on-the-ground conservation efforts for species that still have a chance for recovery.

The odds are slim against any freshwater mussel surviving into adulthood — a one in a million chance, according to Ford of the wildlife service — but those that do can live a century or longer. Hawaii has the most species on the list — eight woodland birds and one plant. By the late s just three remained — a male and two females. After failures to mate them in the wild, the male was captured for potential breeding and died in The two females were never seen again.

Since , 54 species have left the endangered list after recovering, including the bald eagle , brown pelican and most humpback whales. Climate change is making species recovery harder, bringing drought, floods, wildfires and temperature swings that compound the threats species already faced.

How they are saved also is changing. No longer is the focus on individual species, let alone individual birds. Stephen B. Morton for WABE Conservation agencies have worked with the military and with private landowners to restore woodpecker habitat by using controlled burns, since the forests they live in evolved with fire; by creating artificial cavities for the birds to nest in because it can take them years to do it on their own; and by catching the birds and releasing them in other places, since their populations are now more scattered and isolated than they once were.

The efforts have worked. Across the Southeast, some populations of red-cockaded woodpeckers are now in good shape. Still, the proposed downlisting has been met with some concern.

Researchers have helped the red-cockaded woodpecker thrive by, for example, installing cavities for the birds to live in. Morton for WABE For red-cockaded woodpeckers, the service wrote a special rule, outlining specific prohibitions and exceptions.
