Here’s What ‘Pioneer Species’ Can Do to Your Land

A big part of homesteading is properly managing our land. Most of us have a garden, and some of us grow large fields of crops.

And for those of us who don’t, taking care of our land helps to balance the ecosystem, attract beneficial insects and animals, and generally just make things nicer and prettier.

But after years of repeated plantings, or buying a neglected and abused property at a discount, you might be facing a literal wasteland; land that is so messed up, so depleted, so ravaged that nothing will grow in it or grow well.

You’ve got just three options in this case: spend a fortune on improving it mechanically and with amendments, give up entirely, or use pioneer plant species to help resuscitate the land.

If you aren’t familiar with pioneer species, you are in luck because in this article I’m going to tell you all about them and how they can help your garden. Let’s get going…

What Exactly is a “Pioneer” Plant?

A pioneer plant species is one that’s noted for its extreme hardiness, adaptability, and readiness to grow in severely depleted soils.

Pioneer species actually play an important role in ecosystems big and small because they are the first to colonize, stabilize, and eventually repopulate an ecosystem with lots of other plants and even animal life.

As the name suggests, pioneer plants are the first to arrive, the first to start settlement. They’re also the ones that make life possible for other, less capable plants that follow behind them.

Some of the most common pioneer species in America include black locust, alder, cottonwood and pine trees, along with shrubs and grasses like fireweed, sagebrush, sumac and switchgrass.

Pioneer Species Will Grow When Other Plants Simply Can’t

Some environments are so inhospitable to plant life that you won’t see a single sapling, shrub, or blade of grass. Or at least, you won’t until the pioneer species start colonizing them.

One of the easiest ways to see pioneer species in action is to look for truly devastated tracts of land, those that have been ruined by natural disasters or by human activity.

For instance, major flooding, wildfires, mudslides, mass clear cutting and tilling, and even volcanic eruptions can totally obliterate native plants, down to the root and seed.

But, with a little time, in the wake of any of these events, you’ll see some species start to take hold and basically terraform the environment to make it suitable for other plants…

For instance, fireweed (Chamerion angustifolium) is usually the very first plant that will start to spring up in the wake of a cataclysmic wildfire. As
fireweed establishes itself in the now-barren soil, it will start improving it, slowly but surely. This is notable because wildfire-ravages soils have no nutrients, no moisture, and no structure to support other kinds of plant life.

This amazing, but natural, restorative capability can be put be put to work on your land for the same purposes anytime it is badly depleted or barren..

How These Pioneer Species Can Help Your Land

So what can you expect of a pioneer species on your own property? All will offer the following benefits, though they do vary in efficacy by species:

Increased Soil Nitrogen Levels

One of the very best and most well-known positive attributes possessed by pioneer species is that most tend to be nitrogen-fixing plants. Nitrogen-fixers, something well known to seasoned green thumbs, are those that tend to put more nitrogen into the soil than they use.

Typically, this is because nodules in their roots host bacteria that will absorb nitrogen from the air and then deposit a fraction of it into the soil, keeping the rest for the biological needs of the plant.

Even better, these nodules act like little banks of nitrogen, and after the plant is harvested or dies, its roots will begin to decompose in the soil, releasing that huge amount of stored nitrogen. It’s one of the very best all-natural nitrogen amendments you could hope for!

Soil Stabilization and Better Consistency

Most pioneer species, whatever kind of plant they are, offer significant soil stabilization benefits.

Whether they’re shallow-rooted or deep-rooted, virtually all pioneer species have extensive, sturdy root networks that help to lock down the soil and prevent erosion by wind or water.

They’re especially beneficial on sloped terrain or any land that is exposed to strong prevailing winds.

As you probably already know, once erosion carries away the first several inches of topsoil, most of the nutrients that are available to other plants will be gone also.

By locking the soil in place with their roots, pioneer species will improve both the texture and the nutrient composition of this slowly forming topsoil, making it suitable for many other species.

More Shade

As mentioned, most pioneer species are tough, tough plants and can grow in shade, full sun, or anything in between depending on their usual region. But importantly, these plants all provide shade to the surrounding area.

This itself has several benefits depending on the follow-on species which take up residence: the shade provided by pioneer plants lowers soil temperature and encourages water retention by reducing evaporation.

It can also provide partial or dappled shade for delicate species that cannot withstand intense sunlight.

In turn, the plants that get established thanks to the shade will further improve and stabilize the environment for other plants that depend on them, and so on and so on. So much of recolonization and development depends on the shade provided by pioneer species!

Windbreaks

Believe it or not, it doesn’t take much wind to make survival too difficult for many kinds of plants. Aside from the erosion problems we talked about, wind can also scour young and delicate foliage or blow away cover plants and leaf litter that others need to survive.

Once again, because they’re so tough, our pioneer species, particularly shrubs and trees, start to act as all-natural windbreaks that will give their tender cousins relief from the wind’s ravages.

It also has many other benefits for homesteaders because it will cut down on airborne dust and grit and help you nurture that topsoil even more.

If you aren’t happy with the prevailing winds on your property, planting a row of pioneer tree species like birch or alder might be just the ticket. We’ll talk more about different species in just a couple of sections…

Increase Organic Matter in Soil

Pioneer plants are just like every other in that they add a certain amount of organic matter back to the soil. This happens naturally when they drop leaves, blooms, and buds, or when they die and decompose.

In all cases, carbon, nitrogen, and a host of other needed nutrients end up back in the soil where they will be used by all the other plants nearby. This also improves the structure of the soil, making it more amenable to a wider variety of plant, insect, and other animal life.

Improved Water Retention

Lastly, our pioneer species, whatever kind they are, do great things for water management in the area in which they’re growing…

Many of them are themselves highly drought-tolerant because they have to be, and this in turn means you’ll use less water, and won’t worry so much about the soil drying out if you aren’t getting much rain.

They themselves also help lock more water into the soil from the shade they provide, as mentioned, and also from their root networks.

If things are so dry and dusty that no other plant will grow, all you need to do is figure out which species is usually the first to re-emerge in your area and then encourage its growth.

Soon enough, your soil will be holding on to water like a sponge and you won’t struggle to get other plants started.

Pioneer Species are Biome Specific

Before we move on to the list of common pioneer species and you just pick your favorite, I should mention that pioneer species tend to be biome-specific. Naturally, plants are endemic to some areas and not to others, however adaptable they are!

By way of a for instance, in the south, you’ll see blackberries rapidly spread across depleted soil that is disturbed and in the open. Sweet gum trees are famous, or I should say infamous, for colonizing and locking down old, disused agricultural fields.

Elsewhere in the US, like across the Southwest, creosote bushes can be expected to grow just anywhere, along with salt bush which grows readily in disturbed desert. California poppies and Douglas fir trees grow all along the west coast.

On the other hand, some species seem truly universal, like many varieties of alder and birch trees as mentioned, which can be found coast to coast and often in areas which have been ravaged by fires or extensive logging.

Common Pioneer Plant Species

Below is a small, and I do mean small, list of pioneer plant species you could consider depending on where you live.

Talking to the local agricultural or forestry department and your local or the equivalent department at a nearby university is usually the best way to figure out which pioneer species are suitable for your area.

Trees

Alder: Alder trees are adaptable, versatile, and known to be excellent nitrogen fixers, which can rapidly improve soil quality for following plants.

Aspen: Aspens grow very quickly, stabilize the soil just as quickly, and spread through the formation of root suckers. This rapid and steady propagation allows them to quickly stabilize a large area and replenish plant and animal life.

Birch: Birch trees are known for quick growth and equally quick establishment in all disturbed soils, even in places where conditions aren’t suitable for other trees and shrubs.

Balsam Poplar: One of the most commonly seen trees that grows along inundated or flood-prone areas, the balsam poplar is amazingly hardy and resistant to rot.

It also grows surprisingly fast! You can easily recognize a balsam poplar from its heady, sweet, and resinous aroma.

Red Cedar: A North American juniper that grows all across the eastern half of the continent, and one known by many local names, this tree is surprisingly adaptable.

Even in truly horrible, rocky soils, it can take root and grow but will remain a bush for its entire life. As conditions improve, or in good soil, it will grow to some 65 ft tall or taller.

One of the most well-known pioneer species, its interactions with other plant life in various environments are well-documented and many.

Shrubs, Bushes and Grasses

Sumac (Rhus spp.): Sumacs are a family of shrubs that can survive, and indeed thrive, in the worst soil conditions and are important ecologically because they are excellent for preventing topsoil erosion.

Blackberries and Raspberries: The bushes that these delicious berries grow on will quickly spread across and take over disturbed areas of soil, and further help improve local ecosystems by attracting mammals and insects which will eat them.

Big Bluestem: A well-known and absolutely unstoppable prairie grass that grows with the tenacity of dandelions.

Anytime soil has been mechanically destroyed, burned, washed away, or in any other way cleared off, if big bluestem is nearby you can count on it quickly establishing itself and in doing so giving other plants suitable soil to root in.

Herbaceous Plants and Flowers

Fireweed: Fireweed, mentioned previously, is so named because it can spring up out of the soil in the wake of a wildfire that completely obliterates other plant life on the forest floor. In doing so, it helps entire ecosystems recuperate.

Lupine: Better known to some as Bluebonnet, the pretty, tubular clusters of flowers on this plant are instantly recognizable and greatly beloved, but in other areas, it is hated as an invasive species because of its persistence. This is another nitrogen-fixing pioneer species.

Goldenrod: Often mistaken and eradicated for ragweed, goldenrod is readily seen growing in meadows, prairies, and along roadsides in neglected and abused soils, a clue that it can grow almost anywhere.

This species adds nitrogen to the soil in direct proportion to the size of the plant. Huge goldenrods might add too much for following plantings!

Indian Paintbrush: Also known as prairiefire, named so for its bright, vivid red flowers, it is one of the first plants that will grow in disrupted soils, and is critically important for adding diversity to early ecosystem regeneration. It grows all across North America and indeed much of the world.
