The Oregon TruffleTryst Truffière is an attempt to create an Oregon Black Truffle truffière using empirical information from several sources.

We have had some Black Truffles again this year although it appears that there were fewer truffles produced. I'm uncertain if they need very cold weather to produce their fruiting bodies, but our winter had been very mild up to a couple weeks ago when we got a few freezing nights. Once again I haven't found anyone with a truffle dog nearby to see how many truffles might actually be maturing.
This year, but only starting in January, I placed a metal wire flag in each hole where varmits had dug up a truffle (by the smell or bits of truffle left behind) along with any hole larger than an inch in diameter that dead ended at a Fir tree root (likely held a truffle, but not necessarily). The trail cams and video cameras placed in the truffle trees show mice, squirrels, chipmunks, rabbits, possums, racoons, bobcat, coyotes and especially birds frequenting the area and digging in the duff. I have a number of mouse traps placed to try to keep the mouse-type population in check. Surprisingly the birds churn up the ground much, much more than any of the other critters.

As mentioned by a wild truffle collector though an acquaintance, Oregon Black Truffles can continue to mature into late spring. We (and the truffle thieving critters) have still turned up fresh Oregon Black Truffles into the middle of May.

We finally had some success finding Oregon truffles on the property. A few Oregon White truffles were found in an unanticipated area near the barn, occurring naturally. Several Oregon Black truffles were found around older trees than those planted and "innoculated" in 2008. Still, the trees where the truffles were found were "innoculated" by pouring a Black Truffle slurry around the base of the trees at the same time as the 2008 plantings. But the small number of trees and large number of 'critters' that like truffles will likely continue to make for slim pickings

Several of the Doug Fir trees in the main field have had large holes dug next to them, close to the trunks. By the size of the holes I would guess it something larger than mice or squirrels. I also did not notice any sign of insect nests around the trees before or after finding the holes. Bears have been documented digging for, or eating truffles, and we have regular visits by black bears. But I have not yet tested any of the trees to determine if any of them may have black truffle mycelium growing on their roots, or actual truffles.

As part of my Horticulture studies, the trees in the main field were numbered, marked and measured for height and caliper. Three weed abatement treatments were randomly selected. They included recycled paper mats, moisture pourous plastic mats and using a propane torch to keep the weeds from growing around the trees. The final report, converted by Excel into a web page format can viewed HERE

March 2008 --
Less than an acre of field has been set aside on the GCRF property for the attempt. Started in 2008, over 300 Douglas Fir seedlings have been innoculated with Oregon black truffles. Some of the black truffles were wild harvested and some were bought at the yearly Oregon Black Truffle Festival held in Eugene, Oregon. The Douglas Fir seedlings had their roots pressure washed and soaked in a disinfectant. They were placed in a slurry of Oregon black truffles for several days and then transferred to a mixture of peat, perlite, vermiculte and the remaining truffle slurry. After six to eight weeks they were transplanted to the field. Each of the original seedlings was covered with a plastic mesh tube to deter deer and elk browsing. Subsequent plantings without the plastic mesh protection suffered a loss of greater than 80% in the first year. Maybe the elk liked the truffle aroma
Have a great day!
