There is a large body of literature addressing transpiration in 
individual trees and in groups or stands of trees (as well as other 
plants, of course).  A search through any science database in your library 
will probably turn up hundreds of hits if you search for the word 
transpiration in article titles.  I'll give you a couple of good places 
to start, though.

These two papers provide thorough reviews of large-scale 
micrometeorological measurements of evapotranspiration (water loss from 
the trees as well as the understory plants and soil):

Kelliher, F.M., R. Leuning and E.-D. Schulze. 1993. Evaporation and 
canopy characteristics of coniferous forests and grasslands. Oecologia 
95:153-163.

Jarvis, P.G., J.J. Landsberg and B.D. James. 1976. Coniferous forest. In: 
Vegetation and Atmosphere, Volume 2.  Edited by J.L. Monteith. Academic 
Press, London, pp. 171-240.

Recent improvements in heat pulse and heat balance techniques have made 
measurements of sap flow through tree trunks and branches practical.  Any 
recent issue of the journal Agricultural and Forest Meteorology will be 
likely to have an article or two dealing with measurements of 
transpiration in trees using these methods.

These two books both have chapters reviewing methods for measuring 
transpiration in trees:

Pearcy, R., J. Ehleringer, H. Mooney, P. Rundel (eds.). 1989. Plant 
Physiological Ecology: Field Methods and Instrumentation. Chapman and 
Hall, London.

Lassoie, J.P. and T.M. Hinckley (eds.). 1990. Methods and Approaches in 
Tree Ecophysiology. CRC Press, Boca Raton, FL.

Hope this helps.
