Rapid ʽŌhiʽa Death (ROD) currently threatens ōhiʽa lehua (Metrosideros polymorpha) on Hawaiʽi Island. First identified in Puna in 2014, the disease has now spread island wide. Besides direct sampling of trees, environmental sampling could serve as an easier and broader strategy to detect Ceratocystis spp., the fungi causing ROD. Environmental sampling could also help monitor the effect of felling ROD infected trees. We developed Passive and Active Environmental Samplers and deployed them at a property in Puna, where both C. lukuohia, and C. huliohia had been detected, and where the land owner practiced the management method of felling infected trees. We set up 2 Active Environmental Samplers (modified mosquito traps...

The following habitat management areas were used in the creation of this feature class: PHMA: Areas identified as having the highest habitat value for maintaining sustainable GRSG populations and include breeding, late brood-rearing, and winter concentration areas.GHMA: Areas that are occupied seasonally or year-round and are outside of PHMAs.IHMA: Areas in Idaho that provide a management buffer for and that connect patches of PHMAs. IHMAs encompass areas of generally moderate to high habitat value habitat or populations but that are not as important as PHMAs.OHMA: Areas in Nevada and Northeastern California, identified as unmapped habitat in the Proposed RMP/Final EIS, that are within the Planning Area and contain...

Environmental DNA (eDNA) detection tools are becoming increasingly popular for documenting occurrence and distribution of native and invasive species. These tools can allow early detection of new diseases and invasive species and provide critical information for land management. We designed two new samplers for monitoring airborne particulates, including fungal and fern spores and plant pollen, that rely on natural wind currents (Passive Environmental Sampler) or a battery operated fan (Active Environmental Sampler). This dataset contains results of an experiment that was designed to determine probability of detecting known numbers of Ceratocystis lukuohia spores on individual slides in these samplers.

We designed two new samplers for monitoring airborne particulates, including fungal and fern spores and plant pollen, that rely on natural wind currents (Passive Environmental Sampler) or a battery operated fan (Active Environmental Sampler). Both samplers are modeled after commercial devices such as the Rotorod® and the Burkard samplers, but are more economical and require less maintenance than commercial devices. We compared our two new samplers to Rotorod® samplers using Xyleborus spp. boring dust known to contain ROD causing pathogens. The comparison was done in a large outdoor field cage to determine relative effectiveness of the three samplers for capturing windblown boring dust. The dataset contains results...

We placed 23 USGS Passive Environmental Samplers (PES) in a grid that spanned the outbreak and monitored for airborne frass containing Ceratocystis lukuohia and C. huliohia.These data include the latitude and longitude of PES locations.

Besides direct sampling of trees, environmental sampling could serve as an easier and broader strategy to detect Ceratocystis spp., the fungi causing ROD. Envrionmental sampling could also help monitor the effect of felling ROD infected trees. We developed Passive and Active Environmental Samplers for collecting airborne particulates and deployed them at a property in Puna, where both C. lukuohia, and C. huliohia had been detected, and where the land owner practiced the management method of felling infected trees.

October 2017 Update: WY - On October 27, 2017 the WY state director signed maintenance actions for the Wyoming Sage-Grouse ARMPA, Buffalo RMP, Cody RMP, and Worland RMP that changed WY PHMA boundaries, bringing them into consistency with the Wyoming Core Areas (version 4) from the current Governor's executive order 2015-4. The updated PHMA boundaries were also adopted by the Lander RMP.April 2017 Update: UT - The interagency team reconvened in late 2016 to review State of Utah GRSG populations and the BLM’s 2015 and 2016 wildfire data. Of the ten soft triggers and seven hard triggers evaluated, only one population soft trigger and one population hard trigger have been met, both within the Sheeprocks population area...
The BLM GRSG ROD/ARMP/ARMPA habitat management areas include Priority Habitat Management Areas (PHMA), General Habitat Management Areas (GHMA), Important Habitat Management Areas (IHMA – Idaho only), Other Habitat Management Areas (OHMA – NV only), Linkage Connectivity Habitat Management Areas (LCHMAs – NWCO only), Restoration Habitat management Areas (RHMAs – Montana only), and Anthro Mountain (Utah only) from the final plan data in the western U.S. Sixteen Environmental Impact Statements (EIS) were referred to for these datasets, which were updated for UT in April of 2017 and for WY in October of 2017. These data are provided by Bureau of Land Management (BLM) “as is” and might contain errors or omissions. The...
