However, recent studies in California have shown that AR use in remote forest settings has escalated and has exposed and killed forest carnivores.
Anticoagulant rodenticides have been documented as physiological stressors for avian species. Northern Spotted Owl Strix occidentalis caurina critical and occupied habitat overlaps the areas where these studies occurred, yet no data were previously available to demonstrate whether this species was similarly affected.
We investigated whether avian predators are also exposed to these specific pesticides and whether Barred Owls Strix varia may be a surrogate to indicate exposure rates in Northern Spotted Owls.
None of the rodent prey species sampled within the study area were positive for ARs. There were no spatial clusters for either low or high rates of exposure, though we detected low temporal trend early on throughout the study area.
We hypothesize a recent change in land-use toward marijuana cultivation may have led to the increased use of AR in this area. This study demonstrates environmental contamination within occupied Northern Spotted Owl habitat and that Barred Owls can be used as adequate surrogates for detecting these pollutants in a rare species such as the Northern Spotted Brm report on comparative study.
Furthermore, additional studies should focus on whether these pesticides are also affecting prey availability for these forest avian species.
The bulk of these studies are accounts within urban, peri-urban, and agricultural habitat settings where wildlife are the most likely nontarget groups to be exposed to or poisoned by these compounds.
However, emerging use of AR in remote forest settings has recently been documented in the western United States Gabriel et al. The widespread use of AR at illegal clandestine marijuana cultivation sites on public and tribal lands has been a significant source of wildlife exposures in these California habitats Gabriel et al.
Concurrently, accumulating data have demonstrated deleterious impacts from ARs for a rare forest-dwelling carnivore in California, the fisher Pekania pennantias indicated by exposure rates, population survival trends, and direct cause of mortality Gabriel et al.
In California and other western states, fishers inhabit remote forests and require deteriorating mature and old-growth forested habitat structures for offspring rearing.
The fisher has now been established as a sentinel of AR exposure risks to others terrestrial forest wildlife that is of conservation concern Gabriel et al. The level of AR contamination in avian wildlife within fisher-occupied remote forested lands has not been assessed to date.
Its current and historical range and designated critical habitat overlap considerably with fishers as well as marijuana cultivation Gabriel et al. Initially, one of the main factors of the precipitous population decline for NSO was the loss of and modification of its habitat United States Fish and Wildlife Service Unfortunately, illegal clandestine marijuana cultivation complexes have been occurring on private, tribal, and public lands, are increasing throughout California and the Pacific Northwest CorvaButsic and Brennerand often fall within NSO-designated ESA critical habitat and occupied NSO and BO territories Gabriel et al.
Typically, collection of tissues of nonmonitored wildlife populations is restricted to sick, dying, or dead animals discovered haphazardly in the field or near areas where the likelihood of human discovery is high Wobeser These removal efforts provide a rare opportunity to collect owl tissues in quantities not normally available, and that would typically take many years to accumulate.
Thus, this program provides an opportunity to collect biological samples that more accurately reflect the natural BO population exposure. We also investigated if BO can be relevant proxies for NSO exposure, even though there are some differences in their diet. We investigated if BO exposure to AR can be used as an indicator for habitat-wide exposure, and examined whether there are any temporal, seasonal, sex, age classes, or behavioral colonizer vs.
For example, we examined whether spatial pattern of AR exposure were clustered or ubiquitous within the landscape such that source points might be determined and focused conservation measures developed.
We investigated opportunistically collected NSO within or near the BO project area to test if there were differences in exposure rates between the two species and determine if BO can be used as surrogates for NSOs.
We sampled opportunistically collected rodents within the project area to investigate whether these prey are exposed to ARs and if AR-positive rodents are associated with positive owls. Finally, we anticipated that any data generated from these investigations would assist natural resource agencies, researchers, and scientists to investigate whether other species, avian or terrestrial, that use the same prey base as BO or NSO are similarly at risk from AR threats.
These timberlands are large tracts that have restricted access and are bordered by public, tribal, and other private land. These timberlands contain both second- and third-growth conifer and hardwood forests on a to year rotation Hamm and DillerDiller et al.
Habitat characteristics consist of both conifer and hardwood forests, with coast redwood Sequoia sempervirensDouglas-fir Pseudotsuga menziesiiand interspersed tanoak Notholithocarpus densiflorusmadrone Arbutus menziesiiCalifornia bay Umbellularia californicaand red alder Alnus rubra; Hamm and DillerDiller et al.
Tissue collection All BO tissue samples for this study were provided for laboratory analysis from principal investigators conducting lethal BO removal projects on GDRC lands. Barred owls were killed with a or gauge shotgun following Diller et al. Owls were then submitted to the California Academy of Sciences, San Francisco, CA, where in addition to the collection of other ancillary data and museum preparations, a portion of the liver 1—3 grams was collected for AR testing.
We collected data on sex and age classes, behavior colonizer vs.
Resident designated owls were not marked and subsequently it would be difficult to know how long an owl may have been on site prior to collection. However, owls collected at these sites were currently and historically occupied by BO.Ek, Ek, Å.
