This paper describes the use of RPA technology as a complementary method during Southern sea lions (Otaria flavescens) counting in Chincha Sur Island, Ica – Peru, as part of the activities scheduled by the Instituto del Mar del Perú (IMARPE). Colonies of these pinnipeds were mapped and its subsequent classification in the Systems of Geographic Information was carried out in order to make comparisons between direct counting on the field and RPA mapping counts. Total values by direct counting and orthophotos were 2300 and 2700 individuals, respectively. While no significant differences were found between the two methods, by means of digital counting, a better detail of the number of individuals on the females and pups categories could be achieved. The use of RPA constitutes a valuable tool that provides geographical reference of each individual and enables repetitions of the counts by d...

Fire is an important element in the development of ecosystems, however when it is spread out of control in areas such as forests and woodlands, the negative effects to the environment and ecosystems are considerable. The Natural Protected Area of Flora and Fauna of Maderas del Carmen (ANPFFMC) is no exception, so the main objective of this work was mapping the rate of forest fuel from the forest of conifers of the ANPFFMC, through the estimation of dead fuels and the burden of the organic layer. 22 conglomerates were sampled, the vegetation was delimited through the classification of a Landsat-8 satellite image. The results allowed mapping the rate of risk of forest fire through the statistical interpolation method “spline with barriers” generating a barrier of the supervised image interpolation. The average values obtained for 1 hour fuels were 1.22 t-ha-1, to 5.24 hours t-ha-1, for...

El fuego es un elemento de importancia en el desarrollo de los ecosistemas, sin embargo cuando es propagado sin control en zonas como selvas y bosques, los efectos negativos al ambiente y ecosistemas son considerables. El Área Natural Protegida de Flora y Fauna de Maderas del Carmen (ANPFFMC) no es una excepción, por lo que el objetivo principal de este trabajo fue mapear el índice de combustible forestal del bosque de coníferas del ANPFFMC, a través de la estimación de combustibles muertos y la carga de la capa orgánica. Se muestrearon 22 conglomerados, la vegetación se delimitó a través de la clasificación de una imagen del satélite Landsat-8. Los resultados permitieron mapear el índice de peligro de incendio forestal a través del método estadístico de interpolación “spline with barriers” generando una barrera de interpolación con la imagen supervisada. Los valore...
