  • Which species in Boulder are most vulnerable to climate change; which are most like to thrive?
  • This work will take place off-site over the course of the next 12 months. Species investigated will be based on Boulder’s monitoring, with the number of species investigated being around 50. I will use a common tool for conducting climate change vulnerability assessments of species across North America, NatureServe’s Climate Change Vulnerability Index tool. NatureServe’s CCVI tool brings together the information on a species’ biology and ecology with predicted changes in climate and an understanding of a given geography (in this case, the City of Boulder), to make relative predictions as to the vulnerability of the species: extremely vulnerable, highly vulnerable, moderately vulnerable, not vulnerable/presumed stable, and increase likely. When input from multiple experts exists, I will average the output likelihood distributions to ensure that the breadth of expert opinion is accounted for. I will also elicit answers to open-ended questions from experts, compiling answers into a vulnerability narrative. In addition, I will use monitoring data to compare the CCVI predictions to changes in species populations and ranges that we may already be seeing. The data inputs for the tool will come from Boulder records, on-line herbaria, ClimateWizard.org, interviews with experts and a literature review. The results of this work will identify specific indicators to watch for, as well as an understanding of which species will be most important to monitor for the effects of a changing climate. This information will be critical to any decisions as to the management of Boulder’s species and the natural communities of which they are a part.

  • Quantifying Erosion Susceptibility as a Function of Geomorphic Variables, Trail Type, and Use with Implications for Trail Planning.
  • Many City of Boulder Open Space and Mountain Park (OSMP) trails traverse erodible geologic units prone to landsliding and erosion. Erosion susceptibility is a key consideration for trail sustainability, directly related to the OSMP Priority Research Topic: “How do soil types on OSMP relate to trail condition/sustain-ability? Can an index of type vs. sustainability aid in trail planning?” and could be especially important for management of undesignated trails. This project proposes integrating existing OSMP data (LiDAR, trail condition, trail use) with new data (drone collected imagery and structure from motion topography; SfM) across geomorphic process domains (foothills near Hogback Ridge, Wonderland Hill, Dakota Ridge, and Flatiron region) to determine how erosion varies as a function of geomorphic (slope, process domain) and land use variables. Digital elevation models from SfM will be created and used for topographic change detection. In-situ measurements will be taken at key areas of concern, such as undesignated trails. Funding is requested for the fi rst year of study with plans to continue for multiple years to capture how erosion dynamics vary as a function of precipitation regime. Funding will support (1) wages for a graduate student and an undergraduate field assistant to collect and post-process data, and (2) the purchase of minor equipment needed for drone imagery acquisition. This project combines previous geologic and climate research to landscape evolution with a practical question of how to best plan sustainable trail infrastructure in public open spaces.

  • Using stable carbon isotopes to estimate the extent of change in OSMP plant communities and make inferences on carbon sequestration.
  • The relationships between land management and plant community dynamics have always been influenced by climate, but these relationships are now being influenced by directional changes and related environmental drivers that have no historical precedent.  The City of Boulder’s ‘Climate Emergency’ acknowledges that city activities that focus on mitigation, adaptation and sustainability have an urgency and priority not previously emphasized.  Such activities are particularly appropriate for OSMP, whose charter emphasized conservation long before climate change rose to dominate management discussions.  Accordingly, management actions should attempt to direct activities and uses of OSMP to maximize those ecological services that contribute to sustainability.  Natural systems buffer climate change via effects on energy transformations and greenhouse gas production and consumption.  Past land use activities such as tillage and overgrazing have reduced carbon storage, and these can be reversed to some degree. The opportunity therefore exists to use OSMP to contribute to the zero carbon emissions initiative for Boulder. Opposing these increases are losses of soil carbon that are associated with increasing aridity, so understanding potential gains and potential losses is more than an academic exercise. Because the Front Range is a mix of plants with two different photosynthetic pathways whose contributions to carbon storage can be measured using carbon isotopes, this characteristic is proposed to provide an ‘index of change’ that will show the current status of plant communities relative to their historical management legacies. The fact that one photosynthetic pathway is likely superior for carbon storage in climates such as ours can inform ‘restoration-forward’ management activities to maximize carbon sequestration potentials.

  • Restoring for resilience: Assessing the restoration success of flood recovery projects on Left Hand Creek, Boulder County, Colorado.
  • Numerous river restoration projects have been implemented in Left Hand Creek Watershed in response to damages caused by the September 2013 floods. Since 2018, the Left Hand Watershed Center has monitored flood recovery on restored and unrestored reaches throughout the watershed. From 2018 to 2019, we found that restored and unrestored reaches maintained pools, riffles, and accessible floodplains. As expected, riparian condition was less established at restored reaches but was increasing over time. We were not able to determine if instream benthic macroinvertebrate communities were impacted by restoration. This result, among others, may be due to annual variation in hydrology, climate, and discrete impacts to water quality caused by mine drainage or nutrient loading. Multi-year, post-project monitoring is critical to understand whether projects are meeting goals in a dynamic system. This project proposes to conduct a third year of monitoring at two OSMP sites in Left Hand Creek.

  • Monitoring Algal Blooms in the Surface Waters of Boulder County with Satellite Data.
  • The 2019 outbreak of harmful algal blooms in Boulder County underlines the importance of managing how humans and animals interact with waterbodies on OSMP and BCPOS lands. Our proposed research aims to improve the agencies’ capacity to develop targeted monitoring and management strategies by evaluating the historic prevalence of and causal factors behind algal blooms, one of the 2020 priority research topics. Previous water quality monitoring strategies have relied on discrete sampling, which provides data at a single point in time and location. While such an approach provides irreplaceable quantitative information, it does not capture the spatiotemporal variability inherent to algal blooms. In this context, remote sensing—the analysis of multispectral satellite imagery—provides a long-term, spatially explicit perspective on the interannual patterns of algal blooms. For this work, we propose using records from the Landsat and Sentinel satellites to quantify the timing, location, and magnitude of algal blooms in major Boulder County waterbodies from 1999–2020. We will focus on those managed by OSMP and BCPOS and also incorporate major waterbodies managed by other entities due to the inherent connectivity in Boulder County water. We will create a time series of algal bloom prevalence for each waterbody using a selection of remote sensing algorithms from the scientific literature. Notably, these algorithms were developed for larger waterbodies, giving us the opportunity to test and advance the science of algal bloom remote sensing. In addition, we will use a suite of hydroclimatic, physiographic, and land cover variables within a machine learning framework to identify the properties that make certain waterbodies more sensitive to algal blooms than others. While also contributing to the state of algal bloom science, we hope this predictive framework can be used by OSMP and BCPOS to create targeted management strategies for algal blooms in the years ahead.

  • Persistence of fertility control from GonaCon for prairie dog population management in the Front Range, Colorado.
  • Black-tailed prairie dogs (Cynomys ludovicianus) and their presence across Colorado’s Front Range have a long history of human controversy. Prairie dogs are keystone species that are enjoyed by many humans, yet they often carry fleas with sylvatic plague, can be destructive to grassland vegetation and crops, and cause property damage in urban and natural settings. When conflict arises with prairie dogs, trap-and-release, barriers, and lethal-control are commonly practiced. However, contraceptives (fertility control) represent a non-lethal method for prairie dog control that the Prairie Dog Working Group of Boulder wishes to pursue. In Fall 2018, we treated 3 prairie dog colonies in the Front Range with GonaCon fertility control to test if the number of pups produced in Spring 2019 was significantly lowered relative to 3 adjacent (untreated) reference colonies. GonaCon is an attractive contraceptive because it 1) is an injectable and thus low risk to non-target species, 2) is a lifetime vaccine, or nearly so, for wild prairie dogs, 3) is affordable (currently ~$28/ indiv. dose), 4) was found to be effective during our 2018-2019 field trials, and 5) is being evaluated for EPA registration for use against prairie dogs. Herein, we propose to re-survey all 6 sites in 2020 by counting juveniles and adults to determine if the GonaCon vaccine continues to protect the treated colonies or if re-treatment with GonaCon is necessary. Thus, we will test whether the level of GonaCon effectiveness has been reduced in these colonies from 2019 to 2020. We also provide a labor-cost breakdown for GonaCon field treatment. We anticipate that this will be a new, non-lethal method for controlling prairie dog populations that could be implemented by land managers in any area where prairie dog conflict arises and where non-lethal methods are required.

  • What Do Land Managers Think? Identifying Visitor Use Issues and Successful Strategies to Address Them in Colorado’s Front Range.
  • Protected areas (PAs), particularly those adjacent to metropolitan areas, are experiencing ever increasing numbers of visitors. There is wide agreement that PAs provide positive benefits to communities and visitors alike however an increase in visitors may also have negative impacts on the resource and the experience. Physical and social impacts present a challenge to land managers who are often guided by dual mandates, the need to protect the integrity of the natural resource while at the same time provide high-quality recreational experiences to the users. Oftentimes these issues are location specific and land managers will employ different visitor use management (VUM) strategies. The purpose of this study is twofold. First, land managers from land management agencies encompassing Colorado’s Front Range will be interviewed in order to understand what they believe are their top visitor use issues. Second, the aforementioned interviews will also be used to identify effective VUM strategies that land managers have employed to address visitor use issues and what metrics or program evaluations were used in order to understand how the strategy was deemed a success. Over the course of a year, spanning 2020 through 2021, interviews will be conducted with federal, state, and local Front Range land managers. Interview data will be transcribed and coded before being analyzed to identify commonalities and differences in visitor use issues amongst the different agencies. Interview data will also be used to inventory and classify successful visitor use management strategies that have been employed by the various agencies. Results from this study can be used by Front Range land management agencies as a basis for identifying common visitor use issues. At the same time this study will provide a knowledge-based resource that identifies and outlines VUM alternatives or prescriptions that have been employed in the real world and identified as successful.

  • What Drives Spatial Structure and Community Growth of a Controversial Species?
  • Inhabiting the prairie and foothills regions of Boulder County are communities of highly social organisms whose activities shape the landscape. As a keystone species, prairie dogs coevolved with the grassland ecosystems of the Rocky Mountain regions. These social ground squirrels provide important ecosystem functions such as aerating and fertilizing the soil, providing habitat for various plants and animals, and are important prey for predators such as raptors, canids, and felids. The activities of prairie dogs often put them at odds with humans as prairie dogs often colonize lands that are privately owned or are utilized for farming, ranching, or planned development. Monitoring and managing prairie dogs in urban systems is thus important in allowing these animals to perform their critical ecological functions while protecting human interests. Understanding how prairie dog colonies grow and what factors contribute to burrow structure can be helpful for planning and managing this species. To study the way prairie dogs build colonies we propose to study long- and short-term changes in burrow creation and abandonment on The City of Boulder Open Space and Mountain Parks, OSMP, prairie dog colonies. The spatiotemporal presence or absence of burrows on colonies will provide valuable information on how burrow density, extent, orientation, and clustering can be used with likelihood models to predict where future burrow creation will occur and thus how colonies will grow. The results of this study will provide detailed information on current prairie dog demographics in addition to parameters to model colony growth. Collectively, this will inform what management actions could be implemented to most effectively mitigate potential conflicts associated with dog conflicts.

  • Permeable landscapes for climate change adaptation in and around Boulder and Jefferson Counties.
  • The proposed research will inform decision making on open space lands in and adjacent to Boulder County by mapping the permeability of landscapes to adapt to climate change impacts. This project will use a coarse-filter, gradient-based approach to understand landscape permeability (connectivity) among important habitat locations, existing protected areas, or large intact “blocks” of natural landscapes within general ecosystems. This project will be valuable to Boulder County, City of Boulder, and Jefferson County because it will provide critical information about the best strategies to adapt to climate change effects — to inform decision making around protection and restoration activities and evaluate broad conservation strategies through subsequent spatial analyses of the output datasets.

  • How parasitic insect biodiversity can help understand the cascading impact of climate change.
  • Recent studies suggest that global insect biodiversity is declining, largely because of factors associated with rapid climate change. Climate fluctuations will transform plant communities, and the consequences will cascade to affect both herbivore diets as well as the natural enemies that attack herbivores. Without proper survey data, land managers are unable to anticipate how changes in plant and insect communities can affect regional ecosystems. Among insects, the diversity of parasitic insects (i.e., parasitoids) is often the least understood because we lack adequate surveys and morphological identification is difficult without expert analysis. We propose to measure the biodiversity of parasitoids that attack the fall webworm, an important herbivore in forested ecosystems within City of Boulder Open Space and Mountain Park (OSMP) land. We will collect fall webworms within forested and riparian habitats within OSMP from June-October 2020, rear the caterpillars in our laboratory to identify emerging parasitoids, and conduct genetic analyses to determine proper genus and species identification. Our research will enhance our knowledge of insect diversity within OSMP land, as well as adding to a larger survey of fall webworm parasitoids across the US. Our study meets the OSMP priority topic of examining which species are vulnerable or tolerable to climate change, an assessment that requires knowledge of the biodiversity present within OSMP. In addition, we will contribute to the scientific merit of enhancing our understanding of plant-insect ecology. As plant communities change, so too will herbivore diets and these impacts will affect species in higher trophic levels, such as parasitoids and predators. Our study enhances our understanding about the community ecology of a common and ubiquitous herbivorous insect in CO, the fall webworm.
