Ministry of Environment stated that the green areas of Moldova are below European standards. In the European Union the standard of green space per capita is at least 26 m2 (square meted, and the recommendations of the World Health Organization suggests a minimum of 50 m2 per capita. According to data provided by the Green Areas Management Association from Chisinau, the scarcity of green space per capita is currently low, constituting 16 square meter per capita. The total area of forest land in Chisinau today is about 7648.49 ha (19 % from the total area of the municipality). Urban green spaces occupy about 3623.49 ha (24 % from the total area of the city) [5]. Forest vegetation is represented by deciduous forests like those in Central Europe. It turns that in terms of quantity the green spaces situation in the city is good, less their quality. The diversity of bird species in a biotope is directly proportional with the phytocenotic diversity of this biotope. Thus, the investigation shows that the phytocenotic ratios failure and the small number of hollow trees, leads to a small variety of species of birds especially those insectivorous that prefer closed nests.

Material and methods

Quarterly observations were made in period 2009-2014 in urban and ecosystems with a different level and nature of anthropogenic influence. The following research methods of investigations were used:

a) transect method; [1]

b) method of point estimation; [1]

c) mapping method; [1]

d) method of photographic recording;

For the research was used the following equipment: binocular Yukon, digital cameras, camcorder, tracking fixed cameras, which were placed on the ground, dictofon, GPS. Equipment for long distance field research includes magnification telescope 1 x 1000, with monocular night vision, digital camera and 500mm lens.

Results and discussions

The fieldwork research was conducted in the municipality Chisinau ecosystems, there were selected for research the most representative areas, namely: forest parks (Izvor Park, Botanical Garden), dawntawn parks (Rose Valley, §tefan cel Mare, Dendrariu); natural island forests near the city. The open ecosystems from the surroundings of the city being represented by meadows, fallow, wheat crop, corn, lucerne, vine, orchards, sunflower, gardens, riverain biotops and swamp vegetation undergrowth or hydrophilic.

Concerning the Protection of Birds, each of the identified species in the city Chisinau it is framed in the following lists: SPEC List [2], Europe Council Directive (79/409) in regards to the conservation of wild birds [7], Berne Convention, Bonn Convention [7], Law on Natural Areas Protected by State 1538/1998 [6].
