From the abstract:
An understanding of trait-environment relationships is particularly important in the case of invasive species which may alter abiotic conditions and available resources. This study is the first to measure the functional response of riparian plant communities to biocontrol of an invasive species.
Final report on population surveys for SWFL and YBCU in 2018 and 2019, apply existing habitat models to illustrate and predict past, current, and future habitat suitabilities for these two species, and update and standardize classification and mapping of riparian vegetation to reflect recent conditions along the lower 50 miles of the Santa Clara River.
A look at several case studies from conservation practitioners and ornithological social scientists to highlight six core principles of translational ecology - an intentional approach in which researchers and practitioners from multiple disciplines collaborate on conservation management. The authors demonstrate how implementing collaboration, engagement, communication, commitment, process, and decision-framing can lead to improved conservation decision-making and delivery of outcomes applicable to specific management decisions.
Development of a novel repellant compound for the potential management of the northern tamarisk beetle (Diorhabda carinulata). Repellant has been shown to be effective on reproductive adults and alter the behaviors of 1st and 2nd instar larvae. Continued development and field deployment of this repellent compound may provide a new tool for the management of D. carinulata.
The northern tamarisk beetle Diorhabda carinulata (Desbrochers) was approved for release in the United States for classical biological control of a complex of invasive saltcedar species and their hybrids (Tamarix spp.). An aggregation pheromone used by D. carinulata to locate conspecifics is fundamental to colonization and reproductive success.
A presentation by Dan Bean at the 2020 RiversEdge West Conference about new knowledge on aggregation phermones, phenology, and genomics.
Riverine ecosystems are known to provide important habitat for avian communities, but information on responses of birds to differing levels of Tamarix is not known. Past research on birds along the Colorado River has shown that avian abundance in general is greater in native than in non-native habitat.
In this chapter, Carothers et al have three objectives: first, they document the value of nonnative Tamarix as summer habitat for birds compared to native riparian habitats of mesquite bosques and cottonwood/willow, and mixed deciduous gallery woodlands; second, they specifically focus on the unintended consequences to native avifauna of dam construction, Tamarix invasion, native vertebrate colonization of the Tamarix-dominated riparian habitat, and subsequent biocontrol along approximately 300 miles of the Colorado River in Grand and Glen Canyons; and, third, the
"This case challenges the Animal and Plant Health Inspection Service’s (“APHIS”) 2010 decision to terminate, without taking necessary remedial action, the agency’s program authorizing wide-scale release of an invasive species known as the tamarisk leaf-eating beetle (“beetle”) that is having, and will continue to have, devastating effects on the highly endangered Southwestern willow flycatcher (“flycatcher”) and its habitat, including designated critical habitat."

In this 2010 Memo from the United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS), USDA - APHIS terminates the tamarisk biocontrol program.
