Porcelain berry (Ampelopsis glandulosa) is a perennial, deciduous vine that can grow up to 20 feet long and can look very similar to our native grapes. Leaves are alternate, simple, variably shaped (from heart shaped to deeply lobed) with toothed edges, and shiny undersides with hairs only along the veins. The vine produces small greenish-yellow flowers that develop into hard berries in various shades of white, yellow, lilac, teal or green that mature to a bright blue. The pith is a distinct white color.

Porcelain berry prefers areas of full sun to partial shade and it grows in moist, rich soils found along streambanks and forest edges. It favors disturbance and takes advantage of flood damage or bank erosion.

Porcelain berry grows quickly and forms thick mats that outcompete native vegetation for light, water, nutrients and space. Once established, it will climb and shade out young shrubs and seedlings on the forest floor. Seeds are distributed by birds, small mammals and water. A high seed germination rate accompanied by its propagation through root fragments makes this vine species of particular concern and difficult to manage.

Herbicide treatment is the most effective control method for porcelain berry and should include either cut-stump or foliar spray treatments in the fall. Vines can also be manually removed to prevent seed dispersal, but care must be taken to pull out the entire root system to prevent resprouting. Follow up treatments in subsequent years is necessary.

If you see any porcelain berry while you’re at any of your favorite places, be sure to report it to NY iMapInvasives !

Happy Memorial Day Weekend!

Memorial Day Weekend means that our Watercraft Inspection Stewards have started for the season!

Our stewards are placed at public boat launches throughout the region and spend their days educating boaters and recreationalists on the steps they can take to prevent the spread of aquatic invasive species (AIS) into and out of their favorite water bodies.

Before heading out to the water, be sure to follow the 6 steps of Clean, Drain, Dry.

1. Check your boating and fishing equipment for invasive species.
2. Clean any visible mud, plants, fish, or animals before transporting equipment.
3. Drain all water holding compartments including ballast tanks, live wells, and bilge areas.
4. Dry boats, trailers, and all equipment before use in another waterbody.
5. Disinfect anything that came into contact with water if it cannot be dried before reuse.
6. Visit your local boat steward!

A popular ornamental, Japanese tree lilac (Syringa reticulata) is native to eastern Asia and frequently found in yards or urban areas. It escapes cultivation, invading and dominating natural areas such as riparian corridors and floodplains. It is known to form monocultures that can shade out native understory plants and compete with native tree species. It also produces a large seed bank that can threaten biodiversity and ecological sustainability.

Japanese tree lilac is quite larger than its shrubby relatives, growing from 15 to 40 feet tall and about 20 feet wide, with an oval, rounded canopy. The species may be single or multi-stemmed, thus categorizing it as a small tree or large shrub. Its leaves are simple, opposite facing, pointed, and oval to heart-shaped with smooth margins, and slightly downy undersides. Reddish brown, peeling bark is observed on younger branches, turning closer to gray in the plant’s maturity. The bark is mostly smooth with raised blisters and lenticels.

Small saplings can be hand-pulled or dug out. Larger trees can be more difficult to manage, but you can try using a shovel, spade, truck, or tractor. You can use systemic herbicides such as glyphosate or triclopyr on larger lilac trees by applying them to the cut stem, basal bark, or with a hack and sq**rt method. Always follow the herbicide label and federal, state, and local regulations when selecting and applying herbicide.

Alternate-leaved dogwood (Swida alternifolia) is a strong alternative. Both have similar degrees of plant hardiness and feature clusters of white flowers. Alternate-leaved dogwood also has striking fall foliage.

And remember, if you spot any invasive Japanese tree lilac while you’re at any of your favorite natural areas, be sure to submit a report to NY iMapInvasives!

Native to China, wineberry (Rubus phoenicolasius) was introduced in 1890 as root stock for cultivated raspberries. The qualities that made it a durable, reliable fruit producer in the garden are precisely what make it such a tenacious invasive. The species is now found in at least 21 states.

Wineberry closely resembles many native raspberry species with leaves that are alternate, light green, deeply divided into three leaflets, and toothed along the margins. The terminal leaflet is the largest and the underside of all leaves are a pale white color. Wineberry has five petaled white flowers that occur in the spring. Bright red, edible berries follow in the summer. It is differentiated from other raspberry species by the fine red hairs that grow densely on its stems (and flowers) causing a reddish hue to the plant.

Differences from native species: Our native black raspberries have a bluish waxy coating on their stems and their fruits turn purple/black when they’re ripe. American red raspberries have glandular hairs, but aren’t covered in red hairs (like wineberry), and their flowers can have some hairs but aren’t densely hairy. Native blackberries have no red hairs on the stem and have green undersides to their leaves and tend to have 5-7 leaflets.

Small infestations can be managed by digging or pulling. Pulling by hand is an effective method of control for seedlings and small plants. For larger plants, disturbance of the root will encourage re-sprouting. Gloves should be worn to prevent injury from the plants numerous spines. Larger infestations can be treated via foliar spray or cut stump using a glyphosate or triclopyr based herbicide.

If you see any wineberry while you’re at any of your favorite places, be sure to report it to NY iMapInvasives!

🌳Happy Arbor Day! 🌳

To celebrate the day, Kris Williams, Coordinator of the Capital Region PRISM, is here to give you tips on tree planting and care for forest restoration and ecosystem resiliency.

While Planting:
1. Ideally, plant bare root stock the same day you receive it. If that can’t happen, keep them in the refrigerator for up to 2 weeks.
2. Dig a hole as deep and wider than the seedlings root system. If you need to trim the root system to accommodate rocky soils, DO NOT TIME MORE THAN 25% of the root system.
3. Refill the hole while holding the seedling upright, ensuring the roots don’t fold up on themselves and keeping the root collar at the soil line.
4. Firmly pack the soil around the seedling, and water until soil is moist.

Protecting Seedlings:
1. Use a barrier (landscape fabric, mulch, leaf litter) of some kind to prevent competing vegetation (native and non-native) from interfering with the tree’s growth.
2. Avoid the mulch volcano! Mulch packed against the trunk can encourage fungal growth.
3. Utilize a tree tube to prevent deer from damaging the tree and limiting it’s ability to grow.

Post-Planting Maintenance:
1. Remove debris from inside of tree tubes.
2. Remove competing vegetation with 1-2 feet of the tree until tree has established.
3. Make sure tubes are still attached to stakes and at least flush with the ground.
4. Remove the tube when the seedlings trunk is more than 2 inches wide at 6 inches from the ground.

Now let’s get out there, touch some grass, and plant some trees!

Stay on marked and/or designated trails to keep invasive species populations localized for easier management and prevent introduction to new areas. Staying on trails ensures that even if there are invasive species in your boots they won't invade deeper into uninfested areas.
