Studying Biodiversity on Private Lands

CONSERVATION BIOLOGY, Issue 1 2003
Jodi Hilty
Private lands harbor a great amount of biodiversity, including at least some habitat for 95% of the federally listed species in the United States. It is important to conduct conservation biology research on private lands, but our review of the literature indicates that few conservation-oriented field studies are conducted on private property. Based on our success in obtaining permission to conduct research on 43 land parcels in Sonoma County, California, we developed methods to enhance a conservation biologist's chance of obtaining permission to work on private lands. We provide guidelines for researchers to conduct studies successfully on private land with the goal of improving access, data collection, and relationships with private landowners. We also discuss constraints researchers face, such as designing studies appropriate for working on privately owned parcels. In light of the importance of these lands to biodiversity conservation, greater effort should be made to conduct research on private lands. Resumen: Más de la mitad de la tierra en los Estados Unidos es propiedad privada. Las tierras de propiedad privada albergan una gran cantidad de biodiversidad, incluyendo al menos algunos hábitats para el 95% de las especies incluidas en la lista nacional de especies en peligro de extinción en los Estados Unidos. Es importante llevar a cabo investigación sobre biología de la conservación en tierras privadas, pero nuestra revisión de la literatura indica que existen pocos estudios a campo orientados hacia la conservación en propiedades privadas. En base a nuestro éxito en obtener permisos para llevar a cabo estudios de investigación en 43 parcelas de tierra en el condado de Sonoma, California, desarrollamos métodos para mejorar las posibilidades de los biólogos conservacionistas de obtener permisos para trabajar en tierras privadas. Hemos provisto lineamientos para que los investigadores lleven a cabo estudios exilosos en tierras privadas con el objeto de mejorar el acceso, la recolección de datos y las relaciones con los dueños de tierras privadas. También discutimos las limitantes que los investigadores enfrentan, tales como el diseño de estudios adecuados para trabajar en parcelas de propiedad privada. Dada la importancia de estas tierras para la conservación de la biodiversidad, se debería realizar un esfuerzo mayor para llevar a cabo investigaciones en tierras privadas. [source]

Managing the Commons Texas Style: Wildlife Management and Ground-Water Associations on Private Lands,

JOURNAL OF THE AMERICAN WATER RESOURCES ASSOCIATION, Issue 3 2007
Matthew Wagner
Abstract:, As nearly all of Texas' rural lands are privately owned, landowner associations for the management of white-tailed deer and ground-water have become increasingly popular. Deer are a common-pool resource with transboundary characteristics, requiring landowner cooperation for effective management. Ground-water reserves are economically important to landowners, but are governed by the "rule of capture" whereby property rights are not defined. One ground-water association and four wildlife management associations (WMAs) were surveyed to characterize their member demographics, land use priorities, attitudes, and social capital. Members of the ground-water cooperative were part of a much larger, more heterogeneous, and more recently formed group than members of WMAs. They also placed greater importance on utilitarian aspects of their properties, as opposed to land stewardship for conservation as practiced by members of WMAs. If ground-water association members could be more locally organized with more frequent meetings, social capital and information sharing may be enhanced and lead to land stewardship practices for improved hydrologic functions and sustained ground-water supply. This, coupled with pumping rules assigned by the local ground-water district, could yield an effective strategy that is ecologically and hydrologicaly sound, and that allows rural provision of water supply to urban consumers.

Rosette Recruitment of a Rare Endemic Forb (Gaura neomexicana Subsp. coloradensis) with Canopy Removal of Associated Species

RESTORATION ECOLOGY, Issue 1 2002
Linda M. Munk
Abstract Gaura neomexicana subsp. coloradensis Munz (Onagraceae), (Colorado butterfly plant), a short-lived perennial forb, became listed as a threatened species by the U.S. Fish and Wildlife Service in October 2000 because of its small global range and population size. This endemic subspecies consists of only 18 extant populations within southeastern Wyoming, southwestern Nebraska, and northeastern Colorado. Wyoming occurrences are on private land with the exception of three occurrences on F. E. Warren Air Force Base, near Cheyenne. Gaura neomexicana subsp. coloradensis may be displaced by many competitors, including Cirsium arvense (L.) Scop. (Canada thistle), an invasive, noxious weed. In June 1998, three G. neomexicana subsp. coloradensis populations were examined for rosette establishment in the presence of and after removal of associated species. The four study treatments removed: (1) Cirsium arvense, (2) grass and forb canopy and associated litter, (3) grass and forb canopy, litter, and C. arvense, and (4) no removal of associated plant species (control). Mature G. neomexicana subsp. coloradensis plants were evaluated for height, number of leaves, and capsule production. The mature plant characteristics monitored in 1998 were not good indicators of subsequent G. neomexicana subsp. coloradensis rosette densities in the following spring. Recruitment was assessed by counting new rosettes in the fall 1999. Although both G. neomexicana subsp. coloradensis and the exotic C. arvense have comparable habitat, removal of C. arvense did not increase G. neomexicana subsp. coloradensis vegetative growth, seed capsule production, or rosette density. Removal of other forbs, grass, and litter, however, increased G. neomexicana subsp. coloradensis rosette density in the following two years, indicating that canopy removal of associated species can enhance rosette establishment of this rare native. The accumulation of dense vegetative cover and litter associated with the absence of herbivory and fire may contribute to the decline of rare species in rich riparian habitats. Return of herbivory and fire in mesic sites to reduce standing biomass accumulations should be considered in restoring recruitment potential to rare monocarpic species. [source]

Chimpanzee responses to researchers in a disturbed forest,farm mosaic at Bulindi, western Uganda

AMERICAN JOURNAL OF PRIMATOLOGY, Issue 10 2010
Matthew R. McLennan
Abstract We describe the behavior of a previously unstudied community of wild chimpanzees during opportunistic encounters with researchers in an unprotected forest,farm mosaic at Bulindi, Uganda. Data were collected during 115 encounters between May 2006 and January 2008. Individual responses were recorded during the first minute of visual contact. The most common responses were "ignore" for arboreal chimpanzees and "monitor" for terrestrial individuals. Chimpanzees rarely responded with "flight". Adult males were seen disproportionately often relative to adult females, and accounted for 90% of individual responses recorded for terrestrial animals. Entire encounters were also categorized based on the predominant response of the chimpanzee party to researcher proximity. The most frequent encounter type was "ignore" (36%), followed by "monitor" (21%), "intimidation" (18%) and "stealthy retreat" (18%). "Intimidation" encounters occurred when chimpanzees were contacted in dense forest where visibility was low, provoking intense alarm and agitation. Adult males occasionally acted together to repel researchers through aggressive mobbing and pursuit. Chimpanzee behavior during encounters reflects the familiar yet frequently agonistic relationship between apes and local people at Bulindi. The chimpanzees are not hunted but experience high levels of harassment from villagers. Human-directed aggression by chimpanzees may represent a strategy to accommodate regular disruptions to foraging effort arising from competitive encounters with people both in and outside forest. Average encounter duration and proportion of encounters categorized as "ignore" increased over time, whereas "intimidation" encounters decreased, indicating some habituation occurred during the study. Ecotourism aimed at promoting tolerance of wildlife through local revenue generation is one possible strategy for conserving great apes on public or private land. However, the data imply that habituating chimpanzees for viewing-based ecotourism in heavily human-dominated landscapes, such as Bulindi, is ill-advised since a loss of fear of humans could lead to increased negative interactions with local people.
