The goals of this project were 1) to contrast existing mature riparian corridor forest habitats with habitats in areas subject to past and ongoing re-vegetation/restoration treatments and 2) to evaluate responses of select bird species to the differences between habitats now and in the future as the revegetated forests develop. We wanted to develop recommendations to improve future re-vegetation/restoration methodology to increase carrying capacity and mobility for borderlands populations of Gray Hawk, Red-crowned Parrot, Red-billed Pigeon, Rose-throated Becard, Neotropical migrant birds, and other high priority riparian taxa.

Of the vital rates that determine recruitment, breeding propensity (i.e., the proportion of females that lay at least one egg) and nest success appear to have the greatest influence, but breeding propensity remains poorly studied. The few studies that have been conducted reveal it to be highly variable among years (15–77%), likely in response to environmental conditions (e.g., precipitation and wetland availability), and lower than estimates from other dabbling ducks. Thus, quantifying breeding propensity across the mottled duck range in the WGC and identifying factors responsible for its variation remain high priorities for future investigation. Breeding propensity is also among the most difficult vital rates to...

The decline in the monarch butterfly has led to it being considered for listing under the Endangered Species Act. Declines in managed and native bees have also been documented, leading to increased concerns about bee populations and communities, as well as the availability of pollination services for crops and native plants. Similar factors have been identified in the decline of monarchs, native bees, and other pollinators, including habitat fragmentation, loss, and degradation (including milkweed loss for monarchs), and disease/predation, as well as climate change, weather extremes, invasive species, and pesticides. Texas is part of the Southwest breeding region for monarchs, which supports approximately 11% of...

Prioritization for maintenance of intact habitat (i.e., habitat quality rating of Good or Very Good), based on local scale ecological integrity, degree of threats faced, potential conservation opportunities, and conservation value of surrounding landscape. In contrast to ecological integrity ratings; threat, opportunity and landscape rankings are largely based on the range of values of any given indicator across the geography, sorted by quantile. There are some exceptions, particularly for indicators used to develop threat rankings (e.g., urban development risk).Prioritization for restoration of degraded habitat (i.e., habitat quality rating of Fair or Poor), based on local scale ecological integrity, potential...

The mottled duck, a focal species for the Gulf Coast Prairie Landscape Conservation Cooperative, is one of only a few duck species adapted to breeding in southern marshes. A major part of its population spends its entire life cycle within a relatively small coastal area in eastern Texas and western Louisiana. This is a thriving part of the Mississippi and Central Flyways, two of four major waterfowl migration routes in North America. In recent years, the mottled duck’s habitat and surrounding areas have been compromised by urbanization, agricultural development, and changes to the area’s hydrology affecting coastal wetlands. The latter threat includes the ramifications of climate change, such as sea level rise and...

This project resulted in the development of a conservation framework to further the conservation of grassland-shrublands in the area encompassed by the Gulf Coast Prairie Landscape Conservation Cooperative (GCP LCC). The project used the Black-capped Vireo (Vireo atricapilla) as a focal species for developing the five deliverables of this project. Additionally, we included two more avian species of conservation priority (Bell’s Vireo [V. bellii] and Painted Bunting [Passerina ciris]), and an additional three species that are of particular interest to land owners and managers (Northern Bobwhite [Colinus virginianus], White-tailed Deer [Odocoileus virginianus], and Wild Turkey [Meleagris gallopavo]) to ensure that...

Habitat fragmentation is considered to be a leading cause that is responsible for the long-term population declines of Northern Bobwhites. There are numerous factors responsible for habitat fragmentation such as expanding suburbanization, intensification of agricultural and forestry practices, and invasions of exotic plants; the unifying theme is how people use land for settlement and the production of food and fiber. As patches of habitat become smaller and more isolated, populations experience a lower probability of persistence that results in local extinctions, which can lead to larger, and perhaps even regional extinctions. However, we lack a strong empirical and quantified basis that describes the numerical...

Sampling Grassland habitats in Urban, Suburban and Rural areas of Central Texas using a modified GMIT protocol and Data Recorder Protocol provided a baseline of operations and tested various techniques and equipment prior to large-scale implementation. This 6-month effort combined the Urban Monarch project with testing field data collections techniques with those used by several partners (TPWD protocol) interested in determining best practices, tools and methodologies for evaluating and monitoring habitat for monarchs, other pollinators and grassland birds. Tablet data recorders were far superior that other recorders tested, and also were superior to cell phone applications. Several milk weed planted areas were...

Sea level rise caused by climate change is an ongoing phenomenon and a concern both locally and worldwide. Low-lying coastal areas are particularly at risk to flooding and inundation, affecting a large proportion of the human population concentrated in these areas as well as natural communities-particularly animal species that depend on these habitats as a key component of their life cycle. While more local, state, and federal governments have become concerned with the potential effects that predicted sea levels will have on their communities and coastal landscapes, more information is needed on the potential effects that changes in sea level will have on coastal habitats and species.

The decrease in the number of monarch butterflies in eastern populations of the United States has led to a Species Status Assessment by the US Fish and Wildlife Service. This project sought to increase the sampling of milkweed within Texas, through which the eastern population travels during its northern and southern migrations. The goals of this project were 1) to complete milkweed (and monarch egg and larvae) surveys, 2) coordinate with other agencies working on efforts regarding monarch butterflies, and 3) to train students. For goal one, we proposed to use the GRTS sampling points to identify and select sites in eight counties in Texas, however because of the location and landowner issues of the random GRTS...

Flow alteration – from new and existing water supply projects, increased urbanization, and drought conditions – is a pervasive threat to aquatic wildlife throughout the Gulf Coast Prairie region. One species susceptible to this threat is Guadalupe Bass, an economically and ecologically important black bass species endemic to Texas. The area encompassing their range is projected to experience some of the highest population growth in Texas, placing increased demands on the aquifers and watersheds of this region. A previous GCP LCC Instream Flow project conducted by the Southeast Aquatic Resources Partnership (SARP) produced hypotheses about instream flow requirements of native aquatic species that need to be tested....

Our focal species [FS] process and the surrogate species [SS] process as described in the guidance and workshops are similar in some respects and substantially different in others; particularly, the explicit objectives and process of the SS approach are significantly different that the current FS approach, although some of the products may happen to overlap because of some shared values and criteria.Not all FS selected by the GCP LCC Science Team may need to be commensurable with the SS expectations; some species may better fit the needs of other partners that may differ from the goals and approach of the SS process and of USFWS. Also, it is the understanding of many that draft SS guidance and workshop materials...

The Western Gulf Coast (WGC) provides valuable habitat for migratory and resident waterfowl. The mottled duck (Anas fulvigula), a resident species, is highly associated with coastal marsh habitats and relies on these areas for all of its life cycle needs. Habitat loss and degradation due to urban expansion and other human activities have raised concerns for the WGC mottled duck population. Although other threats such as sport harvest (Raftovich 2011), lead poisoning (Sanderson and Bellrose 1986), hybridization (McCracken et al. 2001), and predation (Stutzenbaker 1988, Moorman and Gray 1994, Durham and Afton 2003) may be additional factors in the overall decline of the population, the disappearance of suitable nesting...

Climate, sea level rise, and urbanization are undergoing unprecedented levels of combined change and are expected to have large effects on natural resources — particularly along the Gulf of Mexico coastline (Gulf Coast). Management decisions to address these effects (i.e., adaptation) require an understanding of the relative vulnerability of various resources to these stressors. To meet this need, the four Landscape Conservation Cooperatives along the Gulf partnered with the Gulf of Mexico Alliance to conduct this Gulf Coast Vulnerability Assessment (GCVA). Vulnerability in this context incorporates the aspects of exposure and sensitivity to threats, coupled with the adaptive capacity to mitigate those threats....

Habitat loss and degradation due to urban expansion and other human activities have raised concerns for the Western Gulf Coast Mottled Duck population. This species relies on tidal, palustrine, and agricultural wetlands as well as grasslands for all of its life cycle needs. The disappearance of suitable nesting and brood-rearing habitat is believed to be the primary factor associated with long-term population decline of the mottled duck. One of the first science projects initiated by the GCP LCC was development of a spatially-explicit Decision Support Tool (DST) to help guide conservation and management of habitat for breeding Mottled Ducks in coastal Louisiana and Texas. An important next step is evaluating the...
