1. Introduction
Among the most difficult issues facing conservation biologists are the challenges posed by hybridization and genetic introgression. Early warnings, such as the seminal review of Rhymer and Simberloff (1996), introduced the potential threats posed by hybridization and its implications for biodiversity. Subsequent reviews have produced a variety of additional perspectives, addressing issues such as policymaking to the value of hybrids for conservation to ethical considerations (Allendorf et al., 2001; Ellstrand et al., 2010; Jackiw et al., 2015; Wayne and Shaffer, 2016). What has lacked, however, is a discussion of actual strategies and management guidelines designed to address hybridization from a natural resource conservation perspective. Thus, there has been a lag in the development of standard practices and tactics that can be shared among the conservation community. This is unfortunate, for anthropogenic forces are increasingly altering historical patterns of gene flow, endangering species and reducing biodiversity (Crispo et al., 2011; Rhymer and Simberloff, 1996; Seehausen et al., 2008). The goal of this review is to discuss approaches for addressing hybridization when it emerges as a problem and develop a general framework in which to approach the management of hybrid systems. This includes topics such as measuring risk due to hybridization and integrating principles of genetics and evolutionary biology into monitoring and modeling protocols. Many of these strategies require further examination, however, and I will discuss outstanding needs for managing hybrid systems. Given the complexity of this topic, I also include an overview of relevant terminology. My objective is to provoke discussion about the way hybridization is addressed in conservation circles and facilitate efforts to develop standards geared towards this issue when it becomes a conservation threat.
