Wildflowers After Wildfire

Wildflowers After Wildfire

A Guide for the Santa Cruz Mountains

From fire comes life. Fire can have a remarkable power to reset natural systems, making them healthier and more resilient. Wildfires in 2020 were devastating, but as the ash enriches the soil with nutrients, certain plants—some long dormant—will burst forth in a dazzling display of life. These “fire followers” will be a sight to behold.

Read on to learn about the ecosystems in the Santa Cruz mountains and the rare and special plants and flowers that are likely to flourish this spring.

A Guide for Wildflowers After Wildfire

Produced with the California Native Plant Society

The Santa Cruz mountains are a rich and dynamic place with diverse habitats and landscapes rising from the shores to the ridges. We will explore three key plant communities - Santa Cruz Sandhills, Chaparral, and Redwood Forest - and the special flowers, plants, and trees to look for as fire-scarred landscapes reset and rebound.

What to Know Before You Go

Ready to carefully explore nature? Although areas that burned in the CZU Lightning Complex fire like Big Basin Redwoods and Butano State Parks are closed for safety reasons, many fire follower species can be seen for a few years after a fire when burn areas are safe and open. Here are three unique habitats in the Santa Cruz mountains - Santa Cruz Sandhills, Chaparral, and Redwood Forest - and some of the rare fire following plants we might find in each one.

Santa Cruz Sandhills

Extraordinarily rare and delicate, Santa Cruz Sandhills habitat doesn't exist anywhere else in the world and only 40% of it remains. Once the bottom of the ocean, the Santa Cruz Sandhills are made up of rough Zayante soil filled with sea fossils from the Miocene. These sensitive sand dunes, now miles inland between the wet redwood forests and the beach, support many types of wildlife including rare and endemic species that can’t be found anywhere else. These species have specially adapted to the Santa Cruz Sandhills’ low-nutrient soil and California’s natural wildfires.

More to Look For in the Santa Cruz Sandhills

Santa Cruz sandhill habitat flourishes with wildflowers in the spring that die away before the heat and drought of the summer months. These four plants are endemic and specially adapted to the rare Santa Cruz sandhills habitat, some with silver hairs or coloring on their leaves to reflect sunlight and limit water loss in the hot, sandy area. Without natural wildfire to reset their habitat, their already limited protected habitat degrades and further threatens these rare, fleeting beauties. Recent fires should help to create the ideal conditions for them this spring.

Chaparral

Chaparral is a broad plant community of woody, evergreen shrubs like chamise, interior live and scrub oaks, manzanita, toyon, monkeyflower, ceanothus and sage that are well suited to life in California. In the Santa Cruz mountains, chaparral can be found on the lower parts of the driest, hottest slopes and along the coast in the rare “maritime chaparral”.

Plants in chaparral communities are adapted to low nutrient soil, drought, and of course fire. According to the California Native Plant Society, chaparral is one of the most fire-adapted plant communities in North America. Although chaparral is flammable and burns at high-intensities, fires every few decades are exactly what some of the native plants need to survive and thrive over invasive plant competition. After the canopy is burned away, some chaparral plants will resprout and others, like the rare Brewer’s calandrinia, will emerge from seeds that have waited decades for their chance to shine in the sun. Look for rare, fire following plants that had been sleeping beneath the cover of dense chaparral to awaken for the next few years after a fire.

Fast Fact

More to Look For in Chaparral

Many types of manzanitas grow in chaparral habitats and have interesting responses to fire. Although some manzanitas have a large, aboveground storage system called a burl that they can quickly regrow from, many of the rarest types of manzanitas must be much more patient. These two rare, endemic manzanitas cannot stump sprout and must wait for their seed bank in the soils to be passed over by fire to germinate making this a hopeful time to look for these two threatened species.

Schreiber’s Manzanita

This manzanita has only been found in a few locations on the western slopes of the Santa Cruz mountains including seedlings that grew after a fire in 2009. Its blooms can help you spot it from March to April.

Ohlone Manzanita

Even more rare than Schreiber’s manzanita, this manzanita wasn’t discovered until the 1970’s and has only been found on Ben Lomond Mountain. Although its seeds rely on fires to sprout, if fires happen too quickly the new plants may not produce more seeds in time. It blooms from February to March.

Monterey Pine

One of only a handful of native stands of this threatened, endemic tree can be found in Año Nuevo State Park. Monterey pines need fire's heat to open their cones and leave behind the nutrient-rich ash and sunlight it needs to germinate. Without fire, there is less germination and more pests and pathogens like the non-native fungus, pitch canker, that's plagued them since the 1980’s.

The Santa Cruz Mountains are home to some of the most southern native redwood forests. After clear-cut logging in the late 1800’s, only 5% of old-growth redwoods, the oldest, largest trees, are left. In the Santa Cruz mountains, second-growth coast redwoods often grow along other trees like Douglas-fir and hardwoods like tanoak, live oaks, California bay, dogwood, and madrones. The iconic coast redwood usually grows on the lower slopes, basins, and flat areas of the Santa Cruz mountains where water from rain and fog will collect helping to give the world’s tallest tree all of the moisture it needs. Known as “fog drip”, up to 30% of the moisture in a redwood forest is collected by the trees from fog which can be condensed on leaves and dripped down to the soil and also absorbed right into the redwood leaves themselves. Although studies have shown that fog has been decreasing in the Santa Cruz mountains, leaving redwood forests a little drier and the likelihood of fire greater, redwoods and many other plants in the redwood forest are adapted to wildfire. Coast redwoods have thick, fire resistant bark. If fire does manage to damage a redwood tree, it can resprout from trunks, branches, stumps or roots. Tanoaks and madrones can also resprout following fire. Hollows burned out of a living tree by fire become homes for wildlife, plants, and insects.

Fairy Slipper Orchid

Fairy slipper orchids are native to the Santa Cruz Mountains but not often spotted. Like their greek name Calypso suggests they are typically concealed in dense cover of the redwood forest. As geophytes, these beauties can regrow from their underground storage in corms after a fire.

Blueblossom Ceanothus

Although blueblossom ceanothus are native to the Santa Cruz Mountains, they are not rare or endemic like many of the other fire followers in this guide but their lovely fragrance can be enjoyed year after year as they’ll often spring up long after settling in from a fire.

Dudley’s Lousewort

There is much still to learn about this threatened, rare, endemic plant but what we do know is interesting—banana slug slime is one way its seeds are likely dispersed and it benefits from disturbances like road cuts and fire. It may need bare soil below and a closed canopy forest above, so, keep an eye out along road or trail edges in April to June when it blooms.
