A lot of trees do a sap like substance. Evergreens are great at it but many others work too.

Hope you are not going to wait around for it -- it does take a while! :-)
"During the summer of 1993, several additional articles about the extraction of DNA from amber appeared in Volume 363 of the prestigious British journal Nature. In an article by Raul Cano of California Polytechnic University, San Luis Obispo, DNA was extracted from a 120-135 million-year-old weevil found in Lebanese amber. This discovery of insect DNA is well within the time frame when enormous dinosaurs roamed the earth. In another article by Cano and Poinar, chloroplast DNA dated at 35-40 million years old was extracted from the leaf of a West Indian locust preserved in Dominican Republic amber. The leaf is from the extinct species Hymenaea protera, the probable ancestor of present-day African and New World copal-producing Hymenaea species."

Most trees are producing sap if their bark is cut. But to my knowledge, spruce, pine, fir are the types of trees that produce that more abundently.

Hymenaea and Agathis are two common ones I believe.
