5 Conclusions<br />

It is clear from the preliminary and rather approximate analyses that the Caucasus Protected Areas<br />

network calls for improvement.<br />

Planning of the Econet by considering all necessary parameters (the implementation of which has been<br />

already attempted by WWF) is rather time-consuming and requires much financial support. But until<br />

these plans have been implemented, it is obvious that urgent measures should be carried out for<br />

conservation of the following natural habitats and areas.<br />

(a) Measures should be taken throughout the Caucasus for surviving floodplain forest (formation U)<br />

remnants.<br />

(b) Special attention should be focused to the survival of oak forests in the Caucasus. Furthermore,<br />

urgent measures should be taken for surviving formations H and G remnants, as well as for expanding<br />

the protection of units F166-F168, F170-F172. While prioritising the oak forest conservation needs,<br />

the Areas IX, III, VII and VIII should be also considered.<br />

(c) Protection of all three units of formation R should be given priority; also special attention should<br />

be focused on the Areas I and IV.<br />

(d) Urgent measures should be carried out for expanding protected areas in the Talysh Mountains (area<br />

IX) (see corresponding reference on previous page).<br />

(e) Development of the protected territory in Areas III and V will balance the network existing in the<br />

Great Caucasus and will create a good opportunity for establishing wide transborder cooperation and<br />

for creating a “Great Caucasus Green Corridor”.<br />

(f) Establishment of protected areas within the framework of Area IX will guarantee the survival of<br />

local Colchic relict endemic species and communities.<br />

(g) Establishment of a protected territory in Areas VII and VIII is absolutely necessary for perfecting<br />

the network of southern Caucasus and for survival of forest formations (especially F164, F170, F172),<br />

subalpine forests (part of C46, C47), high mountain wetlands, large mammals and ornithofauna, here<br />

threatened with extinction.<br />

2 Recently, the Hyrcan Strict Nature Reserve (with an area less than 3,000 ha) was replaced by Hyrcan National<br />

Park (21,435 ha), established according to decree of the President of Azerbaijan (February, 2004). WWF is<br />

assisting the Azeri Government in the preparation of a management plan and providing core support for<br />

implementation of infrastructure.<br />
