Plastic is commonly used around trees, particularly young saplings, to protect them from being eaten by browsing animals and to prevent damage from lawn maintenance equipment. Plastic tree shelters also aid reforestation efforts by creating a hyper-localised microclimate that increases humidity, accelerates growth rates, and suppresses weed growth. However, there are environmental concerns associated with the use of plastic, including carbon emissions from manufacturing and plastic waste polluting natural environments and harming wildlife. As a result, some organisations are seeking sustainable alternatives, such as cardboard and British wool, and advances are being made in biodegradable technologies.

Plastic tree shelters increase humidity, reducing water loss and accelerating growth
Plastic tree shelters are widely used in tree planting, arboriculture, and tree care to protect young trees and promote their growth. They are particularly popular in the UK and have been gaining traction in the US since 2000.
Plastic tree shelters create a hyper-localised microclimate, increasing humidity levels around the sapling. This higher humidity reduces water loss through transpiration, allowing the tree to make more efficient use of water. The warmer temperatures within the shelter also accelerate growth rates.
The plastic tubes act as a physical barrier, protecting the young trees from browsing by herbivores such as deer, rabbits, and voles. They also prevent damage from rubbing and protect against chemical spray applications. Additionally, plastic tree shelters provide a barrier against mechanical weeding and the application of herbicides or pesticides.
While plastic tree shelters have been shown to enhance survival rates and accelerate forest regeneration, there are environmental concerns regarding the use of plastic. As a result, biodegradable alternatives made from wool, cardboard, and plant-based materials are being developed and tested.

Tree guards protect saplings from browsing animals and deer
Tree guards are essential accessories when planting trees, especially if you live in an area with deer or other large wildlife. They are also necessary for trees in urban areas. Tree guards protect the bark of saplings from damage caused by animals, chemicals, and garden tools in the early years after planting. Young trees are susceptible to being knocked and nibbled by deer, rabbits, and other animals. Even minimal damage to a tree's bark can be catastrophic, exposing it to diseases and compromising its ability to transport water and nutrients.
Tree guards create a physical barrier that protects the tree's trunk from browsing animals. They are typically made from durable plastic, metal, wood, or biodegradable materials. Plastic tree guards are prevalent due to their affordability and versatility. Spiral guards, for example, are made from durable plastic and wrap around the tree trunk in a spiral, expanding as the tree grows. They offer excellent protection against smaller animals like rabbits, rodents, and deer, as well as minor mechanical damage. The spiral design ensures adequate airflow around the trunk, which is crucial for maintaining bark health.
For larger herbivores like deer, tree defenders offer heavy-duty protection. These guards are taller and more rigid, providing a solid barrier against larger threats. They are ideal for long-term use in rural areas or exposed locations where trees face greater risk from animals or weather extremes. Tree shelters can also be made from biodegradable materials, breaking down naturally into water and CO2, minimising waste in hard-to-reach areas.
In addition to protecting against animals, tree guards can also aid in weed suppression. They effectively suppress weed growth, giving saplings a competitive advantage in acquiring essential nutrients and water. Tree guards can also increase humidity levels around the sapling, reducing water loss and allowing the tree to utilise water more efficiently. Overall, tree guards play a vital role in establishing healthy new trees and contribute significantly to reforestation efforts.

Plastic guards can prevent damage from lawn maintenance equipment
Plastic guards have been used for decades to protect young saplings from browsing animals and aid in reforestation efforts. They create a hyper-localised microclimate, increasing humidity and reducing water loss through transpiration, allowing the tree to utilise water more efficiently. Plastic guards also suppress weed growth, giving saplings a competitive advantage in acquiring essential nutrients and water.
However, a UK study has recommended that planting trees without plastic guards should become standard practice to reduce plastic waste. The study found that the carbon emissions from manufacturing plastic guards and the subsequent pollution from unrecovered guards outweigh the benefits. The breakdown of plastic guards into microplastics harms the natural environment and wildlife.
As an alternative, wood or metal stakes can be driven into the ground several feet from the trunk to protect trees from accidental injury by lawn maintenance equipment. Thick, black plastic drain pipes or other plastic devices can also be slipped around the base of the trunk to provide some protection against string trimmers and mowers.
While plastic guards have contributed to reforestation, the environmental impact of plastic waste is a growing concern. Organisations like the Woodland Trust are trialling sustainable alternatives, such as cardboard and British wool, to phase out plastic guards and promote eco-friendly solutions for tree protection.

Plastic shelters suppress weed growth, giving saplings a competitive advantage
Plastic tree shelters have been used since the 1970s to protect saplings from being eaten by browsing animals and to suppress weed growth. They create a hyper-localised microclimate, increasing humidity and reducing water loss through transpiration, allowing trees to utilise water more efficiently. The shelters also increase temperatures, accelerating growth rates.
Weed competition can be detrimental to young trees, as it hinders their ability to acquire essential nutrients and water. Plastic shelters effectively suppress weed growth, giving saplings a competitive advantage and enhancing their survival rates. This advantage is particularly notable in areas with high levels of grazing animals, such as rabbits, deer, and sheep.
While plastic shelters have proven effective in sapling protection and weed suppression, there are environmental concerns associated with their use. The manufacture of plastic guards contributes significantly to carbon emissions, and they are often left unrecovered in the environment, breaking down into microplastics and polluting natural habitats. This pollution harms wildlife and contributes to the larger issue of plastic waste.
As a result, sustainable alternatives to plastic tree guards are being sought and trialled. These alternatives include cardboard, British wool, and biodegradable technologies derived from starch plants and vegetable sources. While plastic shelters have their benefits, the long-term environmental impact of plastic waste and pollution must be carefully considered.

Plastic shelters are cost-effective, but have a negative environmental impact
Plastic tree shelters have been used for decades to protect young saplings from being eaten by browsing animals and to aid reforestation efforts. They create a hyper-localised microclimate that increases humidity, reduces water loss, and provides warmer temperatures, all of which enhance survival rates and accelerate growth. Plastic shelters also suppress weed growth, giving saplings a competitive advantage in acquiring essential nutrients and water.
While plastic tree shelters require an initial investment, their long-term benefits are often considered to outweigh the costs, making them a cost-effective solution for many. However, there is a growing awareness of the negative environmental impact of plastic tree guards. The production of plastic guards generates significant carbon emissions, and they are rarely collected after use, leading to the issue of microplastics polluting the natural environment and harming wildlife.
The plastic breaks down into microplastics over time, and these tiny particles can contaminate soil and water sources, impacting the health of both ecosystems and animals that ingest them. Additionally, plastic tree guards can hinder the growth of some tree species, leading to weak trunks and small root systems that struggle to support the tree.
To address these concerns, conservation charities and landowners are actively seeking sustainable alternatives to reduce plastic waste. Biodegradable technologies, such as tree shelters made from bio-based materials like starch plants and vegetable sources, are being developed to minimise waste in hard-to-reach areas. Other options, such as cardboard and British wool, are also being explored as plastic-free alternatives.
While plastic shelters have proven effective in protecting saplings and promoting growth, the environmental consequences of their use cannot be ignored. The development and adoption of sustainable alternatives are crucial steps towards reducing plastic waste and minimising the negative impact on the environment.
