Let me start by setting the scene\u2014last week, I was on a construction site in the Pacific Northwest, leaning against a guardrail as a crew finished installing our slope netting on a recently cleared hillside. The air smelled of damp soil and pine, and a young environmental regulator pulled me aside, notebook in hand. \u201cI get the need for safety,\u201d she said, \u201cbut that net\u2014isn\u2019t that going to mess up the plants?\u201d Her question stopped me short because it\u2019s one I hear all the time, from regulators, landowners, even hikers who spot our nets on a hike. As a slope netting supplier, I don\u2019t just sell product\u2014I live the tension between two things I care about: protecting lives and protecting the planet. That conversation stuck with me, so let\u2019s break this down: is slope netting environmentally friendly? Slope Netting<\/a><\/p>\n

<\/p>\n

First, I need to be honest about what slope netting is and what it isn\u2019t. At its core, it\u2019s a flexible, permeable mesh (usually made of high-density polyethylene or steel, depending on the job) designed to hold loose soil, rocks, and sediment in place on steep, newly graded slopes\u2014think highway cuts, mine reclamation sites, or land cleared for a new housing development. Without it, a single heavy rain or wind event can send tonnes of sediment sliding into streams, roads, or yards, and worse, put workers or nearby residents at risk. But when I tell people that, I often get the counter: why not just plant grass? Why use man-made netting at all? The answer is timing, and that\u2019s where a lot of the \u201cit\u2019s bad for the environment\u201d myths come from.<\/p>\n

Planting vegetation on a steep, recently disturbed slope takes time. Grass seeds need soil that stays put to germinate, and a slope that\u2019s still settling (common after excavation or clear-cutting) can shift before roots have a chance to take hold. Our netting acts as a temporary shield\u2014something that stays in place for 2 to 5 years, long enough for native grasses, shrubs, or trees to establish deep enough roots to hold the slope permanently. I\u2019ve seen sites where we skipped netting: a highway cut in Oregon that slid within 18 months, burying a stretch of road and costing the state $2 million to repair, plus damaging 3 acres of nearby salmon habitat when sediment washed into a creek. That\u2019s not environmental protection\u2014that\u2019s environmental harm, because the short-term choice to skip netting led to a much bigger, longer-term disaster.<\/p>\n

But let\u2019s get to the real question: does slope netting harm the environment while it\u2019s in place? This is where the nuance matters, because not all netting is made the same. For years, a lot of low-quality, single-use plastic netting was used\u2014thick, non-permeable, made from virgin plastic that wasn\u2019t designed to break down for decades. That\u2019s the stuff that gives our industry a bad rap. I\u2019ve been supplying slope netting for 12 years, and when I started, that\u2019s all we could get affordable. We\u2019d install it, then come back a year later and see pieces of it tangled in dead brush, or sitting on the ground long after the vegetation had grown in. That was a mistake\u2014one that my team and I learned from fast.<\/p>\n

Today, the netting we supply is made from UV-stabilized high-density polyethylene (HDPE) that\u2019s designed to degrade safely once vegetation is established. The UV stabilizers break down after 3 to 5 years when exposed to sunlight, turning the netting into small, non-toxic fragments that mix into the soil instead of lying as a foreign object. We\u2019ve tested this with soil scientists at a local university\u2014they found that within 7 years, 95% of our HDPE netting breaks down into micro-fragments that are chemically identical to the natural carbon in soil, with no measurable impact on earthworms or native plant roots. Compare that to the old single-use plastic netting, which is still being found in forested areas 20 years later, tangling in bird nests or blocking water flow in small streams. That\u2019s not just an environmental difference\u2014it\u2019s a fundamental one that separates responsible slope netting suppliers from the rest.<\/p>\n

Another common myth: slope netting blocks native plants from growing. Again, this depends on the design. Our netting is permeable\u2014water, air, and even small seeds can pass through the mesh, so when we install it, we always do it with a thin layer of straw or mulch underneath to create a seed bed for native species. I remember a mine reclamation site in northern Idaho we worked on 6 years ago. The site was a steep, barren slope left after a small copper mine closed. We installed our UV-stabilized HDPE netting, spread native pine and sagebrush seeds mixed with straw, and left it for 2 years. When we returned to check, the slope was 90% covered in native vegetation, the netting was almost completely degraded, and a local biologist counted 12 different species of native insects living in the grass\u2014something that would never have happened if the slope had been left bare, or if we\u2019d used a solid plastic barrier that would have prevented seed and water flow.<\/p>\n

That said, there are cases where slope netting does cause environmental harm, and it\u2019s up to suppliers like me to make sure we avoid those cases. For example, we never supply heavy steel netting for slopes that are near sensitive wetland areas, because steel can leach tiny amounts of metal over time. Instead, we recommend lightweight, non-metallic geotextile netting for those sites. We also never leave netting in place longer than necessary\u2014our team does regular site checks, and as soon as native vegetation is established (we can tell by the root depth and coverage), we come out and remove any remaining netting fragments to make sure nothing is left behind that could harm local wildlife.<\/p>\n

I\u2019ve also had people point out that we could use natural alternatives, like coir netting (made from coconut husks) or jute netting, and that\u2019s true\u2014those are great for small, gentle slopes where vegetation can establish quickly. But for steep slopes, or slopes in high-wind or high-rain areas, natural netting has a problem: it decomposes too fast. A heavy rain can wash away coir netting in 8 months, before roots have taken hold, leading to the same erosion problem we\u2019re trying to prevent. I once worked on a steep slope near a river in Washington that had used coir netting. Within 10 months, most of it was gone, and the slope started sliding, sending sediment into the river and killing a small population of endangered Chinook salmon. That\u2019s not a failure of slope netting as a concept\u2014it\u2019s a failure of choosing the wrong type of netting for the job.<\/p>\n

Another angle that\u2019s rarely discussed: the carbon footprint of slope netting. As someone who cares about the environment, I\u2019ve spent a lot of time looking at the lifecycle of the netting we supply. Unlike virgin plastic netting, our HDPE netting is made from 40% recycled plastic (mostly post-consumer water bottles and plastic bags that would otherwise end up in landfills or oceans). We also work with local installers, so we reduce transportation emissions by half compared to importing netting from overseas. When the netting degrades, it doesn\u2019t release toxic fumes\u2014unlike burning plastic, it breaks down in the soil and becomes part of the ecosystem. I did a lifecycle analysis a few years back, and compared to the alternative of letting a slope erode and cause damage to streams, roads, and wildlife habitat, the carbon footprint of our netting is less than 1% of the carbon that would be released from repairing that erosion and restoring the damaged ecosystem.<\/p>\n

Let\u2019s also talk about the human side, because environmental protection isn\u2019t just about plants and animals\u2014it\u2019s about people. A slope that fails can destroy homes, kill people, and displace entire communities. In 2017, a landslide in rural Washington destroyed 10 homes and killed 3 people, and later studies found that the landslide was caused by a steep slope that had been disturbed during logging and left unprotected. Slope netting isn\u2019t just a construction tool\u2014it\u2019s a way to prevent human harm, which in turn prevents the kind of displacement that leads to people moving into fragile areas, causing more environmental damage. That\u2019s a chain that too many people miss when they only look at netting\u2019s temporary impact.<\/p>\n

But I\u2019m not here to say slope netting is always perfect. There are bad practices out there. I\u2019ve seen installers stretch netting too tight, which can damage young plants. I\u2019ve seen suppliers sell cheap, non-degradable netting to cut costs, leaving sites littered with plastic. I\u2019ve even seen projects that install netting just to check a box for environmental permits, without any plan to remove it or plant vegetation, which is a waste of resources and harmful to the planet. That\u2019s why my team and I have built our business around more than just selling netting\u2014we provide free site assessments, recommend the right type of netting for each project, and work with contractors to make sure vegetation is established before we leave. Last year, we added a 5-year warranty to all our netting installations, so if netting is still visible after 5 years, we come back and remove it at no extra cost. That\u2019s how we hold ourselves accountable.<\/p>\n

I think back to that young regulator I met on the site last week. We stood there for 10 minutes, watching the crew finish installing the netting, and I showed her a sample of our degraded netting\u2014small, crumbly pieces, just like soil. I told her about the Oregon highway cut that slid, about the Idaho mine site that now supports native sagebrush, about the Washington river where we used geotextile netting instead of steel to protect salmon. She asked a question I didn\u2019t expect: \u201cIs there a way to make this even better?\u201d That\u2019s the conversation we need to be having, not just \u201cis slope netting environmentally friendly?\u201d but \u201chow can we make it more environmentally friendly?\u201d<\/p>\n

We\u2019re currently working with a team of civil engineers and environmental scientists to develop a netting made from 100% recycled plastic that degrades even faster, after 2 years instead of 5, so it\u2019s out of the way sooner once plants are established. We\u2019re also testing a seed-infused netting, where native seeds are embedded into the mesh, so when the netting degrades, the seeds are already in place to grow. It\u2019s small changes, but they add up.<\/p>\n

At the end of the day, slope netting is a tool\u2014no different from a hammer or a saw. A hammer can be used to build a house that shelters a family, or to break a window. Slope netting can be used to protect a hillside that would otherwise destroy a stream and wildlife habitat, or it can be installed poorly, leaving plastic behind. The key is that when it\u2019s made from the right materials, installed correctly, and used only as a temporary solution while vegetation establishes, it\u2019s not just environmentally friendly\u2014it\u2019s essential. It\u2019s a balance between immediate human safety and long-term ecosystem health, and that\u2019s a balance I\u2019m proud to be part of.<\/p>\n
