Animal damage to plants is a daily reality in my Melville yard. I garden under moderate-to-high deer pressure — I've lost hostas, lilies, daylilies, and vegetable transplants over the years. Getting the ID right matters because the control methods are completely different for deer (fencing, repellents, plant selection), rabbits (hardware cloth, repellents), voles (traps, rodenticides, exclusion), and groundhogs (trapping, exclusion).

Misidentifying the animal wastes time and money. The physical evidence — damage height, cut type, tracks, burrows, scat — narrows it down reliably in most cases.

Deer (Odocoileus virginianus)

Per Rutgers NJAES, white-tailed deer are the most economically damaging vertebrate pest in northeastern landscapes.

Damage signature:

• Height: Above 24 inches; typically 2—6 feet from the ground
• Cut type: Ragged, torn, or shredded rather than clean. Deer have no upper front teeth — they tear rather than cut. Per Penn State Extension, the torn appearance distinguishes deer from rabbit (which makes clean cuts)
• Timing: Most intense in late winter (March—April) when food is scarce and in late summer through fall as deer browse heavily before winter
• What they eat: Hostas, daylilies, lilies, tulips, arborvitae, ornamental grasses, many vegetables. Per Rutgers NJAES, even "deer-resistant" plants will be browsed under high population pressure or in winters with deep snow cover
• Tracks: Two-pointed hoofprints, 2—3 inches long, often in soft soil near damaged plants
• Scat: Small oblong pellets, 3/4 to 1 inch, dark brown to black

Control:

• Fencing: Per Penn State Extension, a physical fence 8 feet tall is the only fully reliable deer exclusion. Shorter fences (5—6 feet) work for gardens in non-suburban settings with lighter pressure; they fail under high deer density. Electric fencing with bait (peanut butter on flagging at the wire height) teaches deer avoidance at lower cost.
• Repellents: Odor-based repellents (Milorganite, Deer Scram, Liquid Fence deer repellent, rotten-egg products) provide moderate deterrence but require reapplication after rain. Per Rutgers NJAES, no repellent works perfectly under high pressure.
• Plant selection: The most cost-effective long-term strategy. Per Rutgers NJAES, plants rated A (rarely damaged) include Russian sage, catmint, lavender, ornamental alliums, foxglove, daffodils, and most ornamental grasses.

Rabbits (Sylvilagus floridanus — Eastern Cottontail)

Per Penn State Extension, rabbits are most damaging in late winter and spring when green vegetation is limited.

Damage signature:

• Height: Below 24 inches (24 inches is rabbit reach standing on its hind legs; snowpack raises this in winter)
• Cut type: Clean, 45-degree cut, as if made with pruners. Per NC State Extension, the clean angled cut is diagnostic for rabbits and distinguishes their damage from deer
• What they eat: Young annuals, vegetable transplants, woody plant bark (especially young trees and shrubs in winter), tulips, young perennial growth in spring
• Tracks: Paired front and back prints; back feet land ahead of front feet; trail is asymmetrical
• Scat: Small round pellets, 1/4 to 1/2 inch, scattered near feeding sites

Winter bark damage: Per Penn State Extension, rabbits girdle young trees and shrubs in late winter by gnawing bark from the base up to their maximum reach (18—24 inches above snowpack). Girdled plants cannot transport water or nutrients and typically die.

Control:

• Hardware cloth cylinders: 24-inch tall cylinder of 1/4 or 1/2 inch hardware cloth around individual plants and young tree trunks. Per Cornell Cooperative Extension, this is the most reliable physical barrier. Raise the height to 36 inches in areas with heavy winter snowpack.
• Chicken wire fencing: 24—36 inches high around vegetable gardens; bury the bottom 6 inches bent outward underground to prevent burrowing underneath
• Repellents: Similar products as deer repellents; require reapplication. Per Penn State Extension, commercial repellents work moderately well for young vegetable transplants but are impractical for large areas

Voles (Microtus spp.)

Per Penn State Extension, voles (meadow mice, field mice) are small rodents (4—7 inches) that cause two types of plant damage: surface runway damage and root/bulb feeding below the soil line.

Damage signature:

• Surface runways: 1—2 inch wide trails of dead grass through lawns and garden beds, most visible in early spring after snow melt. Surface runways appear where voles traveled under snow cover through winter
• Crown and root damage: Plants found dead with roots and crowns eaten. Damaged area is at or below the soil surface. Smooth gnaw marks (vs. deer's torn appearance)
• Bulb feeding: Missing bulbs with gnaw marks on remaining fragments. Voles do not take bulbs above ground — the damage is underground
• Height: At or below soil line; not above ground

What they eat: Roots of perennials, small bulbs (crocus, tulip), lawn grass roots, bark of young trees just below and at the soil line, tree roots.

Distinguishing from moles: Per Penn State Extension, moles produce raised ridges or raised tunnel patterns in lawn and eat grubs and earthworms — they do not eat plant roots. Voles use mole tunnels and do eat plant roots. If plants are dying and tunnels are present, voles using mole tunnels are the likely cause, not moles.

Control:

• Traps: Standard snap mousetraps baited with peanut butter placed perpendicularly across active runways. Per Penn State Extension, this is the most effective control method and is inexpensive
• Hardware cloth cylinders: Around bulb planting areas (bury wire at least 6 inches deep with the bottom bent outward); around young tree trunks
• Habitat reduction: Voles favor dense mulch and tall grass as cover. Reducing mulch depth to 2 inches in winter, maintaining mowed lawn edges around garden beds, and clearing dense ground cover reduces habitat

Groundhogs (Marmota monax — Woodchucks)

Per Cornell Cooperative Extension, groundhogs are large burrowing rodents (5—15 lbs) that can devastate vegetable gardens rapidly.

Damage signature:

• Damage height: Ground level; groundhogs sit to eat and consume entire plants or large portions at ground level
• Cut type: Large bites, irregular; large stems and plant bases consumed; entire young plants removed
• Burrows: Large holes 5—6 inches in diameter with a mound of excavated soil at the entrance. Burrow systems can extend 25—30 feet and have multiple entrances. Per NC State Extension, a fresh burrow entrance with loose soil is a reliable indicator of an active groundhog
• What they eat: Almost any vegetable; favorites include beans, peas, lettuce, tomatoes, carrots, and brassicas; also alfalfa and clovers in adjacent areas

Timing: Active from April through October; hibernate from October to February in the north.

Control:

• Fencing: Per Penn State Extension, hardware cloth 3 feet tall buried 12 inches below the soil surface with the bottom bent outward 6 inches. Per Cornell Cooperative Extension, an electric strand at 4—5 inches above the fence top significantly improves exclusion effectiveness
• Trapping: Live trapping with Havahart-style traps baited with cantaloupe, sweet corn, or apple placed near the burrow entrance. Relocate to wooded areas at least 5 miles away. Check state regulations — some states require permits for relocation
• Fumigation: Gas cartridges inserted into burrow entrances are effective in some states where permitted

FAQ

Something is eating my tulip bulbs before they even emerge. Deer or vole? Per Penn State Extension, underground bulb consumption is voles, not deer. Deer eat the emerging shoots and flowers above ground; they don't dig for bulbs. If the bulbs are missing or found eaten underground with gnaw marks, voles are responsible. Planting tulips in wire mesh baskets is an effective preventive.

My arborvitae is stripped from the ground to about 5 feet up. Deer or rabbit? Per Rutgers NJAES, 5 feet of stripping height indicates deer. Rabbit reach is limited to 24 inches (more with snowpack). The torn appearance of arborvitae tips and the height confirm deer.

I see deer damage and rabbit damage at the same time. Is that possible? Absolutely. Both species are common across much of suburban North America and are active in the same landscapes. Per Penn State Extension, overlapping damage from multiple species is the rule rather than the exception in suburban settings.
