Advantages
Disadvantages
Protection from small and large browsing animals.
Good for deer or elk browse protection.
Bird netting is especially lethal to snakes and lizards.
Collar helps to deter gophers. Screen prevents damage from rabbits and insects.
Good for seeds and small plants that grow slowly.
Most plants tend to outgrow screen in one season.
Requires removal.
One of least expensive methods. Easy installation over plants or planted seed and
secure into soil.
Shades seedlings during critical first months of growth.
Affords protection for first couple of months. Breaks
down after one season.
Reduce animal browsing on tree seedlings.
Requires stakes to hold up tubes. Low branches
become entangled in the webbed protector. They
generally need to be removed.
Shields young plants from herbicide application. Filters sunlight. Protects plants
from mechanical cultivators.
Traps moisture, raising relative humidity and temperature inside tube. Conserves
moisture in arid climates. Protects from animal damage, wind desiccation, ro-
dents, and insects.
Potential for excessive heat inside protector unless tube
is vented.
Protects from animal damage, wind, and chemical sprays. Greenhouse environ-
ment promotes seedling growth. Vented tree protector allows air circulation.
Shelters generally need to be held up by a stake, in
addition to being inserted 2 inches into the ground.
Protects from animal damage, wind, and chemical sprays. Greenhouse environ-
ment promotes seedling growth. Splits to allow fast-growing trees to break free.
Recommend using a stake with bird netting to prevent
trapping birds.
Protects herbivores, herbicide drift, creates microclimate that accelerates early
seedling growth. Produces amplified blue light, increasing beneficial photosyn-
thetically active radiation. Blocks a significant amount of harmful UV light.
Shelters need to be staked. Cannot be reused. May
need to be removed from site. Difficult to remove
weeds inside protector.
Can vary diameter and height easily. Can protect several closely spaced trees in
one enclosure. Browse protection from deer.
Labor intensive to install and remove. Tree limbs can
become ensnarled in wire.
Used to fence off a planting area to exclude deer. 8-foot X-treme Deer Barrier®
fencing is two times stronger than the regular game-deterrent fencing.
Tall wooden posts need to be installed encircling the
planting area.
Shields sapling trees from “buck-rub”/antler damage, rodent damage, and girdling.
Protects from mower and trimmer damage.
Protects tree bark against sun scald, insects, and animals. Protects from mower and
trimmer damage.
Protects tree trunk against rodents, sun scald, severe frost, and windburn.
Protects base of tree from mower and trimmer damage.
