Monitoring for Southern Pine Beetle

Earlier this year, the Invasive Species Management Team kicked off the spring with the installation of several southern pine beetle (SPB) traps at Minnewaska State Park Preserve and a few other locations. Southern pine beetle, Dendroctonus frontalis, is a 2-4mm long bark beetle, reddish brown to black in color, that hails from the southeastern United States and attacks pine trees. The female will locate a host tree, most commonly one with a compromised defense system as noted by the presence of alpha-pinene, a chemical released by stressed trees. The females then release the pheromone frontalin to attract males for mating, as well as other males and females. Males also secrete a pheromone, endo-brevicomin, summoning more beetles to congregate. The beetles enter the trees through cracks in the bark. In an effort to eject the beetle, pine trees will produce resin to push them out. The resulting little, lumpy sap nuggets are called pitch tubes and are a good indicator of SPB infestation. Once in the tree, SPB starts constructing curved tubes, or galleries, in the cambium to lay their eggs in. It is in the cambium that we find the xylem and phloem tissue, which transports water and nutrients through the tree and therefore helping the tree growth. Larvae move to the inner bark immediately after hatching, and then to the outer bark to feed as they mature. When they become adults, they chew round exit holes in a “shotgun” pattern, large enough only to fit a pencil tip. The exit holes are another sign of infestation to be on the lookout for. The chewing of galleries disrupts the flow of water and nutrients, resulting in the needles fading and ultimately tree death in as little as 2-4 months. The Long Island Central Pine Barrens have been particularly damaged by SPB. This may be due in part to the lack of fire as a management technique to thin stands, reducing competition and therefore resulting in healthier trees. Additionally, smoke from fires overpowers the beetle’s pheromonal communication, thus impeding their spread.

Because of how widespread SPB distribution has become, eradication of the species is simply not possible. The main method employed to suppress invasions is the cutting and removal of infested trees. A more proactive method includes monitoring pines for the early infestations of SPB to enable a rapid response to the arrival of SPB; bringing us back to Minnewaska State Park Preserve. The Sam’s Point area of Minnewaska is home to the only dwarf pine ridges ecosystem in the world, making it a globally unique and rare site. Therefore, monitoring for the arrival of SPB is imperative for the preservation of this rare pitch pine barrens as well as more common pitch pine communities of Minnewaska.

Nick and trap

Entomologist Tom Schmeelk with the Department of Environmental Conservation (DEC) came to Minnewaska to hoist the traps and explain how they work. The traps used are Lindgren funnel traps, with a chain of funnels that mimics a tree stem. Several lures, or packets of pheromoneswere placed inside the trap which is then hung in a hardwood tree several feet off the ground and from the trunk. The lures utilized are frontalin, the sex pheromone secreted by females, and endo-brevicomin, the aggregation pheromone secreted by males. In addition, alpha-pinene was attached, a host volatile produced by stressed trees. The beetles are lured to the trap and funneled into a collection cup, the contents of which are sent to DEC to be checked for the presence of SPB.

For those concerned that the traps will attract beetles into the park that otherwise would’ve remained absent, rest assured that these are short-range traps that would only lure beetles within a few mile radius- meaning they only attract beetles already in the area. Being unaware of their presence in the park would be the much bigger risk to the park’s pine dominated ecosystems and all the species that depend on these, including the rare dwarf pines. Last year all the traps remained empty, let’s hope for the same this year!

Want to try snowshoeing? Park experts tell where to go

Don’t let the snow deter you from exploring State Parks – just grab or borrow a pair of snowshoes and head out to the trail.  Go snowshoeing on a trail in a nearby park or try one of State Park staff’s favorite snowshoeing spots.

In western New York, Tina’s favorite snowshoeing spot is at Wilson-Tuscarora State Park located on Lake Ontario in northern Niagara County in Wilson.  This is where you will find the Red interpretive trail nestled along the east branch of Twelve Mile Creek.  As you snowshoe through the changing landscapes, you’ll pass through successional fields, marshland, and finally through a mature forest of old growth beech and hemlock trees.  Keep your ears open for calls of the pileated woodpecker.

At Allegany State Park in Salamanca, Adele recommends the Bear Paw Trail located across the road from the Art Roscoe cross-country ski area on the Red House side of the Park.  Bear Paw Trail is the newest trail built for the snowshoeing enthusiast.  The 2.4-mile long, easy to moderate trail has 15 interpretative sights and runs along the ridge above Salamanca to historic Stone Tower. The trail loops through large stands of Black cherry and White ash trees. Look for small secret plants such as wintergreen and princess pines along the trail. Each Monday evening in January and February, the park offers sunset snowshoe hikes. The Environmental Education Department has a few pairs of snowshoes to borrow during programs.

In central New York, Katie’s favorite part about snowshoeing is how the landscape constantly changes during the winter. Even if you snowshoe at your favorite local park, in her case Clark Reservation State Park in Jamesville, everything looks different in the winter.

After the leaves fall off the trees, you can see so much farther into the woods. You will be snowshoeing along at Clark Reservation, and suddenly notice that the ground drops away not far from the edge of the trail into a steep ravine. You might never notice the ravine in the summer because rich greenery hides it from view. Winter’s arrival reveals forests secrets. Soon though, they are covered up again, this time with ever changing blankets of snow. Nature’s snow sculptures change daily, so you really need to hit the trails often so you don’t miss out!

About once a year, the park gets special permission to host a moonlit snowshoe hike it’s amazing how bright the forest is with the light from a full moon reflecting off the snow. You can even see your shadow! Keep your eyes on the calendar to find out when this year’s Moonlight Snowshoe Hike will be, or come out on your own any day to check out this special place.

Family fun at Wellesley Island State Park, photo by State Parks

At the Minna Anthony Common Nature Center at Wellesley Island State Park, Thousand Islands, Molly notes that there are four trails open to snowshoeing.  Probably the most heavily snowshoed trail is North Field Loop.  Only a half mile long, it meanders through a forest full of white pine trees, passes through a seasonal wetland, and into a forest of towering red oak trees.  School groups explore this trail on snowshoes and the nature center staff lead moonlight snowshoe hikes on the trail throughout the winter months.  There is nothing prettier than snow covered woods on a moonlit night.  The park has both children and adult snowshoes available for rent for $3 a pair.

In the Capital Region, Liz at Grafton Lakes State Park suggests the Shaver Pond trail loop. Just under two miles, it offers picturesque views of Shaver Pond, with a trail winding through forest of hemlock and maple trees over easy terrain.  Inquisitive visitors may see mink or fox tracks along the way.  Trail maps are for sale & snowshoe rentals are available at park office on a first-come, first served basis for $5 for four hours.

At Thacher State Park, the Fred Schroeder Memorial Trail is one of Nancy’s favorite snowshoe walks. This three mile loop in the wilder northern part of the park takes you through beautiful woodlands of mixed hardwoods with stands of spruce and hemlock trees and across a couple of open fields,  without much elevation change.  Midway on the loop, you can take in the scenic snow-covered views from the cliff edge at High Point.  Emma Treadwell Thacher Nature Center rents snowshoes to the public.

In the Hudson Valley, Kris at Fahnestock Winter Park mentions two unique snowshoeing trails. If you’re looking for more rugged terrain, and challenging descents, “Appalachian Way” treks along a ridge line to a stunning overlook of Canopus Lake. The trail “Ojigwan Path” offers the beginner and intermediate snowshoer a snaking walk through hemlock groves and strands of mountain laurel. Both routes take around 2.5 hours to complete. Snowshoe rentals are located in the newly renovated winter park lodge, where you can also warm up with a cup of delicious chili!

Laura D. recommends a snowshoeing trail that will lead you to expansive cliff top vistas, through the globally rare dwarf pitch pine barrens, and around the glacially carved Lake Maratanza. The Loop Road at the Sam’s Point Area of Minnewaska State Park Preserve is the perfect trail for viewing these breathtaking vistas. While on the three-mile Loop Road, stop at the Sam’s Point Overlook, where on a clear day, you can see four states!  Snowshoe rentals are available at the Sam’s Point Visitor Center for $15 per adult and $14 per junior (17 years and under) for the day or $5 to join a public program.

A novice snowshoer will find the modest Mossy Glen Footpath loop just right for a snowshoe trip.at Minnewaska State Park Preserve notes Laura C.  This approximately four-mile route follows the Mossy Glen Footpath as it hugs the edge of the scenic Peter’s Kill stream, winding through quiet forests. At the end of this Footpath, take the Blueberry Run Footpath to the Lower Awosting Carriage Road back to your starting point. This loop begins at the Awosting Parking Lot.
