481 AERIAL PHOTOGRAPHY FOR POCKET GOPHER POPULATIONS 297 pp., Richard S. Driscoll and Thomas C. Watson Rocky Mountain Forest and Range Experiment Station USDA Forest Service, Fort Collins, Colorado 80521 k. 332 pp., ABSTRACT Northern pocket gophers (Thomomys talpoides Richardson) are small burrowing mammals occurring primarily between 98° and 120° west longitude and 36° and 52° north latitude in North America. Over much of this range, the 1. Science species occurs primarily in montane and subalpine grasslands and meadows. In the northern part of this range they are found also in lowland situations. High populations may cause serious soil disturbance and consume much herbage; population control may be required on lands with high intensity multiple o: a test 7: 520-527, management. Large-scale, 1:600 and 1:1200, normal color and color infrared ce 172: aerial photographs were studied to determine if this remote sensing system could be used to assess populations of northern pocket gophers in subalpine grasslands in Colorado, U.S.A. Mounds of soil produced by these animals in late summer, which are highly correlated with population density, were interpreted from the photographs. It was determined that population estimates from the photographs were 97 percent as accurate as estimates made by ground evaluation. ress, England. The 1:600 scale color infrared photographs were most useful. Also, kind of vegetation, relatively high or low, had no apparent effect (P = .05) on the ability of photointerpreters to identify imaged earth mounds. Differences (P = .05) among interpreters were negligible. Yiiversity RESUME Ltd., London. Les Thomomys talpoides (Richardson) du nord sont les petits mammifères creusants qui se trouvent entre la longitude 98° et 120° a l'oeust et la latitude 36° et 52° au nord des Etats-Unis. L'espece se trouve, a travers la plupart de cette region, dans les près montaneux et semialpins et dans les prairies. Dans le nord de cette région, il se trouve aussi dans les plaines. :ion. Science Quand la densité de la population de ces bêtes est élevée, surtout sur les terrains avec l'intensité haute de multigestion, les effets délétères peuvent arriver des troublements du sol et de la consommation de l'herbe, et le :ess, Ithaca, contrôle de la population peut être requis. 1152-1157, On a fait des sites herbacés choisis dans le Colorado, U.S.A., par les photographies aériennes d'echelle large 1:600 et 1:1200 de couleur commune et infrarouge, pour determiner si ce système est convenable pour évaluer les populations des Thomomys talpoides du nord. Par ces photographies, on pouvait déterminer la densité de la population par les monicules du sol que ces betes produisent pendant la derniere partie d'ete. Il était déterminé que les devis estimatifs des photographies étaient 97 percent aussi precis que les devis estimatifs faits sur la terre. Les photographies colorées, infrarouges d'echelle 1:600 étaient les plus utiles. La sorte de végétation (relativement haute ou base) n'avait aucune effet (P = .05) sur la capacité des interprêts photographiques pour identifier les monicules vus. Il y avait aussi, les differences négligeables (P = .05) entre les interprets.
