Fire has always been a part of life in southern California. Climate change and current fire management practices have led to catastrophic losses and impacts to human health, infrastructure and ecosystems, as seen, for example, in the 2018 Montecito debris flow. Indigenous wisdom instructs that rather than suppressing fire, we should seek to be in good relationship with fire. This project centers the voices of Chumash people by revitalizing their good relationship with fire in Chumash homelands. This revitalization comes at a critical time for both fire management and revitalization of Indigenous cultural burning practices in the southwest. The project will enable the recovery and documenting of Chumash knowledge...
Purpose This provisional Biogeographic Analysis Package provides a comparison between the annual Spring Indices First Leaf and First Bloom within the user-selected area of interest. Change in the timing of seasonal biological events (phenology – e.g., leaf-out, migration, and reproduction) is one of the most proximate responses to climate change. Information on phenological changes supports managers in adjusting the timing of activities such as treating invasive species, operating visitor facilities, and scheduling climate-related events (e.g., flower festivals, autumn leaf-viewing). Recent work shows that 53% of natural resource parks managed by the United States National Park Service are experiencing extremely...

Controlling the spread and impacts of invasive species is becoming more challenging as climate conditions change. More relevant information is needed to guide timely and localized management actions for these species to preserve cultural resources and ecosystem integrity. Data products are most valuable when they are developed with input from the people who use them for invasive species management decisions. This project will invite decision makers, Tribal representatives, and natural resource managers to share the social and cultural values that influence their trust and use of data. These shared insights will be used by the project team to shape the format, delivery, and communication of a suite of map products...
Knowledge co-production, a process that involves both creators and users of information in knowledge generation, is growing in popularity in the conservation and ecology fields. While examples of successful co-production are becoming more common, many barriers and challenges remain in this work. Here, we reflect on our experiences in knowledge co-production from three recent case studies, using a prominent framework to understand and improve our efforts at each phase of the co-production process. Our reflections yield insights that may help other scientists seeking to support decision-making. We found that paying particular attention to the composition of the team and connecting with agency representatives early...

Climate projections for the South-Central U.S. indicate increases of 2-5°F in average high temperatures by mid-century, declines of up to 4% in average precipitation, and increases in heatwaves and large rainfall events. This changing, more unpredictable climate makes it difficult to decide which species to plant when, or to know when certain species will bloom and go to seed. A refuge manager might ask: what species should be included in restoration plantings to ensure pollinators will have nectar ten years from now? Or a tribal member might wonder: when is the most effective time to visit prairie remnants to collect culturally significant plant seeds to grow for a restoration project? The Time to Restore project...
This page contains NetCDF files of the Spring Leaf and Bloom Indices spanning 1880-2013. These files were created and are maintained by the USA National Phenology Network (www.usanpn.org). The Extended Spring Indices are mathematical models that predict the "start of spring" (timing of leaf out or bloom for species active in early spring) at a particular location (Schwartz 1997, Schwartz et al. 2006, Schwartz et al. 2013). These models were constructed using historical observations of the timing of first leaf and first bloom in a cloned lilac cultivar (S. x chinensis 'Red Rothomagensis') and two cloned honeysuckle cultivars (Lonicera tatarica 'Arnold Red' and L. korolkowii 'Zabelii'). Primary inputs to the model...

Plants and animals undergo certain recurring life-cycle events, such as springtime flowering or migrations between summer and winter habitats, that are often strongly controlled by changes in environmental conditions, including climate. Because species interact, shifts in one species’ phenology can have cascading effects throughout entire food webs and ecosystems. Recent advances have helped grow the body of literature surrounding phenology. We now know, for example, that invasive species often show greater flexibility in the timing of their phenological events, enabling them to outcompete native species as climate and environmental conditions change. Natural resource managers recognize that changes in phenology...

The USA National Phenology Network has available a series of gridded products enabling researchers to analyze historical and contemporary data related to the Extended Spring Indices. The Extended Spring Indices are mathematical models that predict the "start of spring" (timing of leaf out or bloom for species active in early spring) at a particular location (Schwartz 1997, Schwartz et al. 2006, Schwartz et al. 2013). These models were constructed using historical observations of the timing of first leaf and first bloom in a cloned lilac cultivar (S. x chinensis 'Red Rothomagensis') and two cloned honeysuckle cultivars (Lonicera tatarica 'Arnold Red' and L. korolkowii 'Zabelii'). Primary inputs to the model are temperature...

Phenology is the study of recurring plant and animal life-cycle stages which can be observed across spatial and temporal scales that span orders of magnitude (e.g., organisms to landscapes). The variety of scales at which phenological processes operate is reflected in the range of methods for collecting phenologically relevant data, and the programs focused on these collections. Consideration of the scale at which phenological observations are made, and the platform used for observation, is critical for the interpretation of phenological data and the application of these data to both research questions and land management objectives. However, there is currently little capacity to facilitate access, integration and...

The impacts of climate change are widespread and accelerating. It is daunting for resource managers to determine how to use increasingly limited staff time and funding to conserve species and ecosystems. The Refugia Research Coalition is a national framework that brings together researchers and managers to identify and develop conservation strategies for “climate change refugia”, areas that remain relatively buffered from contemporary climate change over time and enable persistence of valued physical, ecological, and socio-cultural resources. Expanding on previous work carried out in the Northwest and Northeast regions, this project will produce a list of priority species and habitats, generated by local and regional...

This datafile consists of a subset of plant phenology observations drawn from the USA National Phenology Network’s National Phenology Database (www.usanpn.org). The data were collected by citizen and professional observers and archived and distributed by the USA National Phenology Network. Protocols are available in Denny et al. (2014). This datafile consists of plant phenology observations that were used in an effort to construct predictive models of phenophase transitions using accumulated growing degree days based on PRISM daily minimum and maximum temperature data. The phenology data were queried from the USA National Phenology Network on 9-25-16.
