Jake F Weltzin
Jake joined the US Geological Survey in 2007 to design and implement the USA National Phenology Network. Since 2015 he has also served as the Program Manager for the Status & Trends Program in the Ecosystems Mission Area.
Jake’s interest in natural history developed as he grew up in Alaska and served as an exchange student in the Australian outback. His interests range broadly -- from natural resource management to ecological- and ecosystem-level research -- across a variety of systems ranging from deserts to grasslands, savannas to forests, and even to wetlands.

Jake is interested in how the structure and function of plant and animal populations, communities and ecosystems respond to global environmental change, including atmospheric chemistry, climate change, and biological invasions. He also studies how scientists understand and describe changes in ecosystems over space and time, from monitoring, to data management and analysis, to delivery of ecological knowledge and information to stakeholders. Current interests include citizen science, enterprise tools for monitoring, data visualization and delivery, and ecological forecasting.
Science and Products
Pollinators are crucial contributors to our environment and society by enhancing plant diversity in wild lands and providing food for humans in agricultural settings. Some three-fourths of all native plants in the world require pollination by an animal, most often an insect, and most often a native bee.
North American bats face unprecedented threats including habitat loss and fragmentation, white-nose syndrome, wind energy development, and climate change. NABat is an international interagency program designed to monitor bat distributions and abundances on public and private lands, and provide trend data at the state, provincial, tribal, regional, and range-wide scales.
WLCI is a long-term, science-based program focused on assessing, conserving, and enhancing fish and wildlife habitats while facilitating responsible energy development through local collaboration and partnerships. We provide multidisciplinary scientific and technical information to WLCI partners and work to advance the overall scientific understanding of ecosystems in southwestern Wyoming.
The USA National Phenology Network is a national-scale science and monitoring initiative focused on phenology, which is the study of seasonal life-cycle events such as leafing, flowering, reproduction and migration, as a tool to understand how plants, animals and landscapes respond to environmental variation and change.
With 2015 marking its 50th anniversary, the BBS continues to provide critical science-based estimates of population change on more than 600 continental bird species annually to improve our understanding of how these federally entrusted species respond to environmental variation and ecosystem change.
