Diagnóstico ecológico y fitosanitario de un parque urbano del área metropolitana de Guadalajara, México

Urban parks are open spaces for public use, where we can find human relations of leisure, recreation, sports, community living,among others, activities. They also provide benefits, through ecosystem services. In the Guadalajara Metropolitan Area, urban parkshave not received enough attention. Traditionally, it was assumed that the trees that comprise it, must be developed without anyintervention of forest management or at most plantations in which very little is intervened with protection and silvicultural work toachieve their establishment and good development. The park of "La Solidaridad Iberoamericana'' is an ecosystem where treespredominate, it is immersed in a densely populated area and offers facilities for recreation. Hence the importance of this work,which provides lines of action aimed at promoting and managing the park's urban forest. The leading goal of this work was todevelop a comprehensive diagnosis to identify forest management needs. The methodology consisted of making a stand for thepark, establishment of 108 sampling sites of 500 m², survey of dasometric, silvicultural, biodiversity and phytosanitary variablespresent in the trees. The results are: five stands were defined, the main species susceptible to mistletoe were Jacaranda mimosifolia,Bahuinia americana and Casuarina equisetifolia. The main phytosanitary problem is Struthanthus interruptus, a mistletoe speciesthat affects trees, followed to a lesser extent by Psittacanthus calyculatus. The biodiversity and richness of tree species are 20, theybelong to 16 different botanical families, standing out Fabaceae, Bignonaceae, and Salicaceae. The silvicultural management needs detected are pruning and thinning; 18.6% of the trees require pruning to raise the crown, 75.4% require sanitary pruning, 19% of the trees must be felled, since they represent a danger of falling due to rain and strong winds.
