Conservation classes
The plants were divided on basis of conservation
status into five classes (Khan, 2013).
Result
In the present study the conservation status of trees in
Tehsil Katlang were determined. Total 45 species
belonging to 34 genera and 25 families were recorded
(Figure 4). The Moraceae was dominant with 6
species followed by Myrtaceae, Rosaceae, Rutaceae
with 4 species and Mimosaceae with 3 species.
Asclepiadaceae, Papilionaceae, Rhamnaceae and
Solanaceae with 2 species. Alliaceae, Apocynaceae,
Cactaceae, Caesalpinaceae, Cupressaceae, Euphorbiaceae,
Lamiaceae, Meliaceae, Oleaceae, Poaceae, Punicaceae,
Sapindaceae, Sapotaceae, Simaroubaceae, Tamaricaceae
and Vitaceae with single specie (Table 2). The plants
were divided on basis of conservation into five classes
i.e. endangered, vulnerable, rare, infrequent and
dominant. In the present investigation among 27 trees;
10 species were found to be vulnerable, rare (8
species), endangered (5 species) and 4 species were
Infrequent while in 18 shrubs; 10 species were
vulnerable and 4 species were both rare and endangered.
It is decisive that on the basis of conservation status no
species was found to be dominant (Figure 5).
