Biodiversity monitoring is the main way to understand resource dynamics, the living conditions of protected objects, and the effectiveness of conservation, as well as the main means to construct and manage national parks and protected areas. The technical status of biodiversity monitoring reflects the management ability and technological level of national parks and protected areas. Compared with other industries and other areas of the forest and grass industry, the technological progress of animal resources and biodiversity monitoring is lagging behind, which has become a major constraint to the construction of high-quality national parks and protected areas. This paper mainly focuses on the development of monitoring technology, including a summary of the defects of existing technology, an assessment of current technology, and suggestions for future development. In addition, this paper also introduces the performance of the author"s research products, ‘monitoring pass’ and solutions to existing technical defects and problems. The aim of this study is to promote the development and improvement of national parks and protection monitoring technology in China, to help the construction of national parks and natural protection.
