Areas of Conservation Emphasis (ACE) version 3: A California
Department of Fish and Wildlife conservation analysis tool - April 12, 2018, 1:00 p.m. - 3:00 p.m.
Presented by Melanie Gogol-Prokurat
The California Department of Fish and Wildlife (CDFW) Areas
of Conservation Emphasis (ACE) project is a non-regulatory tool that brings
together the best available map-based data in California to depict
biodiversity, significant habitats, connectivity, climate change resilience,
and other datasets for use in conservation planning. ACE compiles and analyzes
information from multiple CDFW data products, including the California Natural
Diversity Database (CNDDB), California Wildlife Habitat Relationships Program
(CWHR), the Survey of California Vegetation, as well as other mapped
information found in the Biogeographic Information and Observation System (BIOS)
to create products that can help inform landscape-scale conservation decisions.
The terrestrial data is summarized and displayed in a standardized hexagon (2.5
2) grid, and the aquatic data is compiled by HUC12 watershed. All
ACE datasets are available in an online map viewer or for download. CDFW has
just completed ACE v3, a major revision and update.
ACE Biodiversity metrics are based on 1) species location
information from CNDDB and other species survey datasets for 354 rare and/or
endemic vertebrate species and subspecies, and 1672 rare and/or endemic plant
taxa; and 2) species range or habitat distribution models for 791 common and
rare native species of amphibians, birds, fish, mammals, and reptiles, and 183 families
of aquatic macroinvertebrates. ACE combines information on species occurrence
locations and species habitat distribution models in a standardized way to show
the distribution of biodiversity, species richness, rarity, and endemism across
the state and in each ecoregion. ACE Significant Habitats brings together
information on important habitats such as rare vegetation types, oak woodlands,
wetlands, and riparian areas based on vegetation maps and other landcover
datasets, as well as information on focal species key habitat areas. ACE
Connectivity brings together information on natural intact lands, habitat
linkages, and wildlife corridors. ACE Climate Change Resilience brings together
information on locations expected to be relatively buffered by climate change
impacts. These datasets provide an overview of the conservation elements potentially
present at a given location based on best available data, and can be viewed
together with State Wildlife Action Plan (SWAP) conservation targets,
stressors, and juxtaposition to existing conserved lands in the ACE viewer to
provide a broad overview of information important to conservation planning and
research. We will describe the data now available in ACE v3, and will present
example use-case scenarios.

Recent Advances in Effective Bat Mitigation in California - March 21, 2018, 1:00 p.m. - 3:00 p.m. Presented by Dr. Dave Johnston
Dr. Dave Johnston provides an overview of bat mitigation in California including assessing habitat for bats, determining the various types of potential impacts, and mitigating for impacts from mining, tree removal, bridge work, and roof replacement.
Dr. Johnston discusses various steps for effective mitigation strategies and discusses how knowing the natural history of a species is often critical for success. Potential impacts to bats from noise and light pollution and the appropriate mitigation are also discussed.
Location: Natural Resources Building, First Floor Auditorium - 1416 Ninth Street, Sacramento, CA (or via webinar)
