The palm grove is a great ensemble of ph�nicicols gardens, as different from each other. Each orchard has its particular characteristics, as floristically that faunal. We are witnessing in previous decades to continual degradation of ecosystems "palm grove" whose main cause is anthropogenic. Our study would be to protect non-functional biotopes, based on biological indices. Thus, we generally distinguish maintained orchards, moderately maintained and non-maintained. The diagnosis of a biotope health status was assessed through its biocenotic composition. Significant differences both from the point of view floristic that faunistic were identified by comparing two ph�nicicol environments; one maintained grouping 33 floristic species and 45 faunistic species, other non-maintained with 13 plant species and 17 faunistic species. Floristic richness increased the number of trophic categories of which 11 are registered in maintained environment. We stipulate that the biocenosis present in an environment can be a source of information on the state of an ecosystem and its functioning. Keywords: Palm grove, fauna, flora, trophic regime, biological balance.
