Bonny Doon Ecological Reserve

Recently I went to the moon. At least it seemed like it. Walking through a portion of the 600 acres of burned out  vegetation from the , I couldn’t help but think of it as a moonscape. The misty fog was lifting after a night of rain and milky sun warmed us as we walked through the burned out trees. It was surreal and made even more so by nature’s valiant effort to regrow and fill the void left by the fire. At ground level the earth was bursting with life. Every inch of sandy soil was growing or sprouting something alive. You could almost hear it if you listened closely.

The fire destroyed 3 homes and severely damaged another. About 60% of the Bonny Doon Ecological Reserve burned. It’s amazing to see the recovery already taking place. The bracken ferns came first, followed by the endangered Bonny Doon manzanita some of which have sprouted from their bases while 6" tall starts from seed are everywhere. The burned gnarled trunks rendered the landscape otherworldly and magical. Pockets of manzanitas that were spared by the fire were in full bloom dripping with clusters of delicate, white urn-shaped flowers. This manzanita is endemic to the Santa Cruz sandhills and does not occur anywhere else on the planet. Did you know that manzanita leaves are still used in Russia in the tanning industry due to their high tannic acid content?

Golden chinquapin sprouted from the bottom of their mother tree and around the base are scattered the burr-like spiny bracts that contained a sweet tasting nut. California broom, so unlike the invasive Scotch broom, blanket the ground. They are one of the first plants to colonize an area after a fire and their quick growth can aid in erosion control as well as soil enrichment, through their relationship with the nitrogen producing bacteria, Rhizobium, in their roots.

Large stands of Bush poppies were growing in between the huge manzanita trunks. Bush poppies are common in sandy or rocky soils, often in burned out areas. These plants were taller than I’ve seen elsewhere in this area reaching 4-5 ft  Come spring they are going to be spectacular when they bloom in April-July but they also flower a bit in all seasons.

Silver-leafed lupine were doing their part to help the soil both by stabilizing with their deep roots and building up the nitrogen supply with the bacteria in its root nodules. Warty-Leaved ceanothus grew in large patches and were getting ready to bloom with their deep purple flowers.

Yerba santa were plentiful being an opportunist in the area and finding lots of open areas. They easily sprout from  from the roots after the fire as well as seeding themselves.

This area is a fire ecology and will come back just fine. It’s an extraordinary maritime chaparral habitat with a dense concentration of unique endemics that have emerged here in response to tens of thousands of years of periodic fires.
