Is it true that sap from evergreen trees is acidic? If
true, do they cause the prevention of undergrowth?
The sap of conifers could be acidic. However, the lack of seedlings,
herbaceous layer could be due to more prominent factors such as lack of
sunlight and water. Decomposition of needles and other organic matter
would probably be larger in affect upon the acidity of the soil.

Acidic pine needles retard the growth of some other plants beneath pine
trees. See a good plant ecology book for more information.
