“…Popular media and scientific literature continue to report the negative environmental and consequent economic imp a c t s o f t h e f o r a g i n g b e h a v i o r o f f e r a l s w i n e (Engeman et al 2003(Engeman et al , 2004b(Engeman et al , 2007aPimentel et al 2005;Morthland 2011;Tegt et al 2011). Increasingly too are researchers' efforts describing the negative impacts feral swine have on native ecosystems globally, as well as land managers' attempts to mitigate their damages (e.g., Campbell and Long 2009).…”

Feral swine are estimated to annually cost hundreds of millions of dollars in economic loss to property and agriculture in the USA, while their ecological consequences remain largely unmeasured. Using submeter-accurate Global Positioning System technology over a multiyear project, we are quantifying in a novel way the spatial and temporal attributes of swine rooting damage within 587 ha of ecologically sensitive wetland plant communities at Avon Park Air Force Range in south-central Florida. We delineated damage polygons from 0.0023 to 4,335 m(2) and were able to document recurrent damage through time at most sites during each assessment. For each polygon, we also estimated the age of damage and assigned to it a severity index, qualities of the rooting in which we detected changes in proportions over time. Spatially explicit damage assessments at fine scales conducted over several years can assist land managers in determining effects of rooting on rare plant populations, and will allow investigators to hypothesize what factors are driving patterns of this disturbance across ecologically sensitive plant communities.

“…Although there are examples of invasive species becoming pests (i.e. Chapman 2003;Elliot 1989;Engeman 2004), keystone species which play a major role in an ecosystem are rarely regarded pests in their native ranges. Examples of keystone species that affect farming activities include pikas (Ochotona curzoniae) on the Tibetan plateau (Smith and Foggin 1999) and prairie dogs (Cynomys spp.)…”

The European rabbit is a growing problem for agriculture in parts of its natural range. In this paper, our aim was to use historical records over two periods within the last 50 years to analyze trends in the number of requests made for rabbit control in Central Spain. We gathered data on rabbit control applications made for 1967(derived from Rabbit and Hare Control Authorization Records) and corresponding information for 2005 from Technical Hunting Plans. Technical Hunting Plans are currently the official mechanism to apply for rabbit control licenses in the country. We show that although only 4.2% of municipalities requested to control rabbits in 1967, this proportion was 71% in 2005. Given that there is no evidence of rabbit increases in the study region, we suggest that other factors may explain the observed increase in such requests. We argue that sport hunting, which has risen significantly since the 1960ssupported by the fact that the shotgun was the most requested method of control, is the main reason for this rise in rabbit control requests. We recommend the creation of a more detailed form, similar to that used in Spain in the 1960s, in which the reason(s) for a rabbit control request can be clearly declared. The use of such a document would allow managers to obtain a more realistic assessment of rabbits as a pest.

“…We often think about endangered species more from the population dynamics perspective (Morris et al 2002, US Fish andWildlife Service 2007) than monetary depending on the species (Rubin et al 1991). Species where conservation is in direct conflict with human economic activities, either through loss of production or damage, are commonly evaluated economically (Montgomery et al 1994, Engeman et al 2004. We suggest that the opportunity cost, or allocation of resources to one species rather than another, should be considered in order to maximize the use of conservation dollars (Shogren et al 2001).…”

We evaluated the consequences of different predator management strategies and the subsequent effects on time and cost to recovery for federally endangered Sierra Nevada bighorn sheep. Based on data collected during 1995-2009, we used stage based demographic modeling to estimate vital rates in three isolated herds, accounting for sampling error and variance. Using those vital rates we predicted the time and associated cost for the population to meet delisting goals. We found recovery time increased from 17.3 to 28.6 years using a density independent model and from 25.9 to 38.6 years using a density dependent model for different mountain lion management strategies. Commensurate cost increases of over 10 million dollars (unadjusted cost) result in either case. Our study suggests that appropriate levels of predator management will result in shorter recovery times and reduced cost of recovery through ensuring the availability of translocation stock. To be most effective, mountain lion management strategies should be population-specific because of underlying differences in predation rates for different herds.
