other parks, alleys, green plantings it affects positively a micro climate as the
whole city as my microdistict . What trees can we see here? There are a lot of
different trees such as oaks - 448, ash- trees -335, lindens -140, larches -100, elms-
5, maples-14, in total -1000 trees. Trees is an important means of ecological
protection. They absorb carbonic gas and enrich the air with oxygen. How pleasant
is to take cover from the scorching sun in the boiling hot, hide from a strong wind
and rain under the crones of trees. The temperature of the air in the summer is 1-2
degrees lower, the humidity -2-4% above , than in the open spaces of the city.
Besides, trees are home forto a great number of different birds living in the
crones of them :, not only well-known sparrows, daws, ravens, starlings, pigens,
but also ouzels and even woodpeckes. How often we saw these funny birds from
the windows of our school! And if you are tired you can sit on one of the benches
in the alley and listen to the cheerful singing of birds, feed pigens and titmouses.
Look! We have reached our following stop – a monument to an outstanding
antifascist , Ernst Thelman . can see flowers at the bottom. Let,s us continue our
excursion and our movement along the alley and our talk about the tress growing
here.. We are representing the next ecological fragment of our route.. The
importance of the trees in the life of our city is inomorous, but, unfortunately, they
suffer greatly because they are exposed to negative influence of indusrtial plants,
transport . Students of the 10 class of our school have researched the trees of the
the alley and founded that per hour in the morning approximetlyapproximately 50
cars pass along the Sophiisky bulevar.Sophisky bulvar. It,s very adversely for the
trees. Students have learnt that in 2008 year 2 oaks, 19 ash-trees, 13 lindens, 4
larches were lost.
Causes of death are different: illnesses, negative influence of anthropogenous
environment, a bad treatment of people. Our school is located in the alley of the
Sophiisky boulevardSophisky bulvar, so we try to care of our microdistrict to
make it nice.nicer. We organize clean-up campaigns, tree-planting days, design
and make objects at school, such as bird feedres, earth day-wreaths.
