A comparison of campfire impacts and policies in seven protected areas A comparison of campfire impacts and policies in seven protected areas
Using resource-monitoring data from seven protected areas, the effectiveness of three campfire policies—campfire ban, designated campfires, and unregulated campfires—were assessed based on the number of fire sites and the amount of tree damage. Results indicate that unregulated campfire policies permitted substantial numbers of fire sites and tree damage in campsites, although fire bans...

Quantifying production of salmon fry in an unscreened irrigation system: A case study on the Rangitata River, New Zealand Quantifying production of salmon fry in an unscreened irrigation system: A case study on the Rangitata River, New Zealand
Diversion of out-migrant juvenile salmon into unscreened irrigation and hydroelectric canals is thought to have contributed significantly to declining populations of anadromous salmonids in the Pacific Northwest but is seldom studied in detail. Here we describe a program to study the fate of Chinook salmon Oncorhynchus tshawytscha fry diverted into the unscreened Rangitata Diversion Race...

A new species of Lonchophylla Thomas (Chiroptera: Phyllostomidae) from Ecuador A new species of Lonchophylla Thomas (Chiroptera: Phyllostomidae) from Ecuador
We describe Lonchophylla orcesi, sp. nov., from the Choco, a region of high biotic diversity, endemism, and rainfall along the western Andean slopes and Pacific lowlands of Colombia and Ecuador. One of the largest known Lonchophylla, it occurs sympatrically with at least two other species of Lonchophylla including the similar, but somewhat smaller L. robusta. We also recognize L. concava...

Population trends of North American sea ducks as revealed by the Christmas Bird Count Population trends of North American sea ducks as revealed by the Christmas Bird Count
Relative to other waterfowl, sea ducks are not well understood, yet evidence from a variety of analyses suggests that as many as 10 of the 15 species of North American sea ducks may be declining in population. However, because of the difficulty of conducting surveys of breeding populations and the lack of range-wide winter surveys, few data are available to assess the population trends...

Estimating the number of animals in wildlife populations Estimating the number of animals in wildlife populations
INTRODUCTION In 1938, Howard M. Wight devoted 9 pages, which was an entire chapter in the first wildlife management techniques manual, to what he termed 'census' methods. As books and chapters such as this attest, the volume of literature on this subject has grown tremendously. Abundance estimation remains an active area of biometrical research, as reflected in the many differences...

Bottomland hardwood establishment and avian colonization of reforested sites in the Mississippi Alluvial Valley Bottomland hardwood establishment and avian colonization of reforested sites in the Mississippi Alluvial Valley
Reforestation of bottomland hardwood sites in the Mississippi Alluvial Valley has markedly increased in recent years, primarily due to financial incentive programs such as the Wetland Reserve Program, Partners for Wildlife Program, and state and private conservation programs. An avian conservation plan for the Mississippi Alluvial Valley proposes returning a substantial area of cropland...
