Martani sides have mainly sweet furrowed by deep valleys, due to the presence of torrential streams dry for most of the year.
The high degree of permeability of the limestone rocks and the presence of the fault system have allowed the establishment of a deep groundwater flow and complex. In some cases, water erosion has produced very deep ravines, with sinkholes due the dissolution of limestone; there are also cavities and caves.
The tops of Martani are mostly rounded and have grassy features. The evergreen forests, which are characterized primarily by Holm, are very interesting. There are also the Strawberry Tree, the Elah, the mastic tree, the Erica, the Olivastro and the beautiful Aleppo pine.
As for the fauna, its diversification is linked to the variety of plant environments examined above.
Among the invertebrates are to remember two splendid insects: the Strawberry Tree butterfly (Charaxes jasius) a beautiful large diurnal butterfly characterized by typically tropical colors, unfortunately more and more unique, closely related to the Strawberry tree (Arbutus unedo), a plant by which the caterpillar can survive; and Cerambice of Beech (Rosalia alpina), a rare beetle cerambycida, marked by a blue livery light with ash-dotted elytra by velvety black spots, which survives thanks to the beech woods. Among amphibians we note the beautiful and rare salamander and the small spectacled salamander. Regarding Reptiles is to point out the Cervone and the common viper.
Among the birds are to be recommended: the buzzard, the sparrowhawk and other diurnal and nocturnal birds of prey. It also noted the presence of rare species like the green woodpecker, the great spotted woodpecker, the kingfisher and the lonely sparrow. The Mammals, though present in a number of species, are difficult to observe for the "non-specialist". So their presence is only noticed by careful analysis of the soil.
Among them there are: the hedgehog, the squirrel, the fox, the weasel, the polecat, the Faina and Tasso.
In the mid-eighties , thanks to some initiatives of the Umbria Region, it was create the Martani Trekking.
It is a "double-loop" or "eight form" path which spreads over different terrains: on the grassy ridges and on ridges cloaked forests, among the small medieval villages of historical roads and paths: a path suited to the three types of hiking on foot, horseback and mountain biking.
