Introd  uction  Avenue trees are the trees which are grown on road   side. They provide cool air and shade to the  passengers.avenue  passengers.avenue trees keep the air fresh , prevent   soil erosion and reduce noise ,air and thermal   pollution.the greenery of the avenue tree make the area attractive and appealing. Different types of  animals get food and shelter from the avenue tree.  Some of the common avenue avenue trees trees cultivated cultivated in our  country are cassia fistula,dalbergia sissoo , azadiraeta indica ,acacia arebica, albizia labback  etc. the study of effect on avenue trees on temperature can be an interesting subject. Therefore , study of effect of avenue trees on temperature under canopy and outside has been  selected for the present project.

 Material  required  1)an area with avenue trees 2)thermometer  3)beaker  4)water  5)pen 6)notebook 

 Experimental   Procedures 1)Find out an area with sufficient avenue trees and  area without trees. 2)Take 3 beakers 3/4 th filled with water.Put one thermometer in each of them. 3)Place one beaker under the avenue tree,2nd  beaker  near the avenue tree in the open,the 3rd beaker in a the area without trees. 4)Record the temperatures of the trees areas in the morning,noon & evening and record the data in the observation table.

Observations SL  NO. 1) 2) 3)

TIME

Morning  Noon Evening

TEMPERATURE UNDER  AVENUE TREE 20.8 °C 26 °C 23 °C

TEMPERATURE  NEAR AVENUE TREE 21.3 °C 26.5 °C 23.4 °C

:

TEMPERATURE IN OPEN AREA 22.1 °C 26.9 °C

24.1 °C

CONCLUSION   Area which is without trees has maximum temperature,and the area nearby avenue trees show  comparatively low temperature while the area under  the avenue tree exhibit least temperature.The low  temperature under the tree is due to the shade and  loss of water vapour through transpiration.

 AIM  TO STUDY THE EFFECT OF AVENUE TREES  ON TEMPERATURE UNDER A CANOPY AND OUTSIDE .
