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 .
