“…Nevertheless, the number of successful recoveries of T&E species under the ESA remains small (Rohlf 1991, U.S. FWS 1996a, Dobson et al 1997, Foin et al 1998, Beissinger and Perrine 2001, Abbitt and Scott 2001, Stokstad 2005. Furthermore, the number of listed T&E species grows faster than the available funds and hence, many observers claim, the U.S.…”

The necessity to develop a priority system to guide the allocation of resources to the conservation of endangered species is widely recognized. The economic theory of biodiversity has established a framework to do so, and has identified priority criteria that should be considered when making conservation decisions. This paper uses a randomeffects ordered probit model of endangered species recovery to simulate the effects of reallocating conservation funds among species listed under the Endangered Species Act according to these criteria. Our results suggest that if the goal of conservation policy is to preserve a diverse set of species, reallocating conservation funds according to criteria identified by economic theory would yield an improvement over actual spending patterns without significant tradeoffs in terms of overall species recovery.

“…Fish and Wildlife Service (USFWS) or the National Marine Fisheries Service (NMFS) with developing recovery plans for these species. The ultimate success of both the ESA and recovery planning has been called into question because of the limited number of species that have been recovered (Foin, Riley, Paley, & Anitra, 1998;Tear, Scott, Hayward, & Griffith, 1993), and scholars have identified many potential obstacles to the success of these plans, including social factors such as communication. Michaelidou, Decker, and Lassoie (2002) presented a general model of recovery viability that identified both ecosystem and community factors as well as external social, economic, and political forces.…”

“…In south Florida, considerable loss of habitat due to development has threatened animal and plant species, and the federal government has sought to address this problem, in part, through a multi-species recovery plan. The problems of south Florida may be particularly relevant to the rest of the country, since habitat loss has been identified as a primary threat to species nationally (Czech, Krausman, & Devers, 2000;Wilcove, Rothstein, & Dubow, 1998;Foin et al, 1998), specifically through land-use conversion that alters habitat (Tear et al, 1995).…”

“…Conservation efforts directed by vague biological data about targeted species are often unlikely to be successful (Tear et al 1995;Foin et al 1998;Boersma et al 2001;Clark et al 2002;Gerber and Hatch 2002). Understanding population processes is therefore vital for conservation efforts, as basic knowledge about population dynamics can help biologists focus monitoring efforts on evaluating factors likely related to population decline (Campbell et al 2002).…”

A simulation model of the Devils Hole pupfish population using monthly length‐frequency distributions

et al. 2013

The Devils Hole pupfish, Cyprinodon diabolis, is a federally-endangered fish that is endemic to Devils Hole, a discontiguous part of Death Valley National Park in Nye County, Nevada. Due to its status, Devils Hole pupfish monitoring must be non-obtrusive and thereby exclude techniques that require handling fish. Due to a recent decline in pupfish abundance, Devils Hole pupfish managers have expressed a need for a model that describes population dynamics. This population model would be used to identify vulnerable life history stage(s) and inform management actions. We constructed a set of individualbased simulation models designed to explore effects of population processes and evaluate assumptions. We developed a baseline model, whose output best resembled both observed length-frequency data and predicted intraannual abundance patterns. We then ran simulations with 5 % increases in egg-larval, juvenile, and adult survival rates to better understand Devils Hole pupfish life history, thereby helping identify vulnerable life history stages that should become the target of management actions. Simulation models with temporally constant adult, juvenile, and egg-larval survival rates were able to reproduce observed length-frequency distributions and predicted intraannual population patterns. In particular, models with monthly adult and juvenile survival rates of 80 % and an egg-larval survival rate of 4.7 % replicated patterns in observed data. Population growth was most affected by 5 % increases in egg-larval survival, whereas adult and juvenile survival rates had similar but lesser effects on population growth. Outputs from the model were used to assess factors suspected of influencing Devils Hole pupfish population decline.
