Cover: A wolverine (Gulo gulo) in Kronotsky Biosphere Reserve on Kamchatka. The wolverine is a rare species, patchily distributed across large landscapes, whether in a Russian nature reserve or the Rocky Mountains of the United States. Rare species present a challenge for monitoring, but a power analysis can help ensure monitoring goals are feasible and illuminate cases when meaningful monitoring can be accomplished only through collaboration across multiple entities. When data are limited, a simulation framework can be used to investigate the power of monitoring protocols to detect trends in population abundance over time with occupancy-based methods (see pages 52–62).

Photographer: Igor Shpilenok travels across Russia documenting its nature reserves, national parks, and wild places. Shpilenok drove the creation in 1987 of a strict nature reserve, the Bryansk Forest Nature Reserve, which conserves floodplains, forests, and nesting habitat of the rare Black Stork (Ciconia nigra). During the 11 years Shpilenok managed the Bryansk Forest Nature Reserve, he and his colleagues led the designation process for another 12 nature reserves. Shpilenok is a regular contributor to National Wildlife, Ranger Rick, Russian Life, National Geographic-Russia, Canadian Wildlife, Geo-Germany, and BBC Wildlife. In 2006 and 2009 his photographs were awarded first prize in the BBC Wildlife Photographer of the Year competition. In 2008 Shpilenok and his wife, nature writer Laura Williams, published their memoir The Storks' Nest.
