This episode ofNature Calls, Conversations from the Hudson Valley is a retrospective look at one of the early radio interviews from our precursor show, “Digging in With Master Gardeners”, aired on WGXC, 90.7 FM. Teresa and Jean interviewed Master Beekeeper and Emeritus Master Gardener Volunteer Linda Aydlett. The original was aired as episode 14.

Linda Aydlett has been a beekeeper for over a decade, tending from two to thirty hives in various years. She got started at a workshop by the Catskill Mountain Beekeeping Club, studied via books, internet and Youtube videos, and then became a Master Beekeeper through Cornell University. Linda tells us there is a special relationship between bees and their keeper, quoting author Mark Winston : “The world slows down to focus on bees and their world.”

There are 20,000 bee species worldwide. Honeybees are the only insect providing food eaten by people. They are most commonly managed by people. There are twenty sub-species and they are now found in all habitable parts of the world, but are not native to North America. Some key details about honey bees include:

• they forage over an area of several miles
• they rarely sting because they will die if they do
• they use their knees to carry the pollen from flower to flower
• their role in the ecosystem is enormous.

One third of our food supply relies on the presence of pollinators. Honeybees can be directly connected to 75% of fruit crops and 53% of seed production. Direct production from honey bees includes honey. It is nectar brought back to the hive and stored at an 18% moisture content. It takes millions of miles of flight and visits to two million flowers to produce 1/12 of a teaspoon of honey. Propolis is a glue produced from the sap of evergreens for maintenance of the hive. It is also valuable to humans for certain antimicrobial properties, and is also used as a wood varnish. Beeswax is excess nectar, and is the infrastructure of a hive. Humans have multiple uses for the wax, including the popular beeswax candles. Even the venom has a use. Although its removal kills the bee, the venom is used to inject “heat” into arthritic joints.

Bees are often considered livestock and overseen by departments of agriculture in many states. Nectar is the reward to the bee for transporting pollen from flower to flower. Linda goes on to describe the fascinating details of a forager bee's life. They find the flowers (and are flower “constant” while a particular flower is in season), and collect the nectar. They return to the hive and transfer it to another bee. They also perform a “waggle dance” to transmit information about direction of the nectar source. Linda describes both the dance and how researchers decoded it in 1927.

There are three castes of bees, and Linda describes the duties of each in detail, from the queen to the drone to the worker. There is considerable drama to the choice and emergence of new queens. Learn about a substance called royal jelly which is exuded from the foreheads of nurse bees to feed the queen larvae. The larva of worker bees emerge to assume one or more of the duties of a worker bee. There are, in addition to nurse bees, mortuary bees, ventilator bees, guard bees and others. Eventually each of these can be promoted to a forager bee, usually for the last half of their life (eight weeks on average). There are even some bees known as winter bees. They are born in September or October and can survive the winter. They are of necessity less active and their main duty is to keep the hive warm... around 90 degrees F. They can unhinge their wings and then shiver to produce heat, all the while rotating from the inside to the outside of the bee cluster. New egg laying starts in February and March when activities revert to traditional good weather behavior. Ideally, there was enough honey stored in the hive for the population to survive the winter.

Bees are fascinating species. Learn more about them in the upcoming Part 2 of this conversation.

This episode continues our conversation with Kristopher Williams of PRISM and a frequent guest on Nature Calls: Conversations from the Hudson Valley. Kris is our go-to expert about all things invasive. We have talked to him about invasive plants, insects and diseases. Today we asked Kris to tell us some of the success stories about his long career as an environmental advocate. We have spoken to Kris in previously aired episodes 23, 24, 31,and 189, in case you want to look a little deeper into his work. First a reminder of the definition: PRISM stands for Partnership for Regional Invasive Species Management. It is one of eight regional districts in the state devised by NYS DEC and funded by the EPA to try to control the onslaught of invasive species of all kinds into the state.

Part 2 features another success story. The Hudson Crossing Park in Schuylerville, NY is on the Washington/Saratoga County line. It's an island in the Battenkill near Lock 5 of the Champlain Canal. Over a period of several years, a volunteer group sought advice from the PRISM organization. It began with a speaking engagement on the actual site, combined with a “park walk” to assess the trail network, pavilion and gardens already in place. This is what Kris calls the outreach component, educating interested people. A year later, the group asked for advice on how to manage the woodland in the park. The next year they asked for maps to divide the area into plots. Another year later, the woman leading the efforts attended a regional partnership meeting and reported a successful grant application and heavy equipment acquisition. The progress continued. They designed a “tree promenade” of native trees and underplanted it with native shrubs. The funding magic continued as more local businesses participated.They ended up with fifty trees and thirty shrubs, planted by an army of volunteers and local businesses along with members of the PRISM team. This can be replicated, usually with a “driver”, a motivated volunteer. There is a link here to the park's website.

Tim then changed the subject to an invasive he's particularly irked by... Japanese stilt grass. Possible solutions were discussed, including some failures. It all ended with a positive note, though. Kris had cleared stiltgrass from an area and replanted with natives. The following season checkup revealed NO stiltgrass. The natives had prevailed. As an added note, there is some study going on regarding the effects of tannins from Hemlocks being a deterrent to stilt grass. So hope remains in the control of invasive species. Stay tuned!

This episode brings back our frequent guest, Kristopher Williams, of PRISM (Partnerships for Regional Invasive Species Management). Eight PRISMs exist across New York State and work to prevent or minimize the harm caused by invasive species on our environment, economy, and health and welfare of residents. PRISMs are intended to coordinate invasive species management functions including coordinating partner efforts, recruiting and training citizen volunteers, identifying and delivering education and outreach, establishing early detection monitoring networks and implementing direct eradication and control efforts. Regional partnerships with nonprofits, municipalities, conservation groups and volunteers are devised to cast the widest net for control over an enemy that recognizes no artificial borders. The Capital Region Prism ranges from the Catskills to the Adirondacks, encompassing eleven Counties and three million acres.

Kris is our go-to expert about all things invasive. We previously have talked to him about invasive plants, insects and diseases. Today we asked Kris to tell us some of the success stories about his long career as an environmental advocate. Our earlier conversations with Kris have aired in episodes 23, 24 and 31, in case you want to look a little deeper into his work.

The team has five core members and sixteen seasonal members on staff. Their mission is to coordinate all available resources, public and private, along with volunteers, to combat the multitude of invasive problems and organize alternatives. Their mission includes massive public lands and advisory status for privately owned properties. They act as the glue, Kris says, to hold all entities together. PRISM delivers science and educational programs for maximum impact, and always keeps in mind the different objectives of local and statewide groups. Tim asked Kris for some success stories, since we have discussed so many problems in the past. Kris listed some of the lasting beneficial effects:

• people achieve self-actuation by becoming aware of and seeking resolutions to invasive incursions;
• celebrating local impacts to inspire further efforts;
• there is now an exposition on invasives every two years;
• college-level programs are now available educating about invasives and remedies.

The conversation drifted to the emotional part of treatment of invasives. Most of them got here because they were introduced for a particular feature, and then “escaped” because they were prolific and had no natural enemies. There are also “sleeper” invasives, a new designation. These are known invasives that are still being sold to the public. Unfortunately sixty-one per cent of all invasives are still being sold. There is a patchwork of states regulating and actively banning sale of certain plants.

One success story Kris talks about is the Grassland Bird Trust. Washington County had a 20,000 acre trust facing the issue of dealing with invasives. A management plan was devised and a board established. Kris detailed the progress over several years as a management system was put into place and assessed for success year by year. Tim asked about what happens with much smaller efforts, and Kris described available training in IPM (integrated pest management) and land management as well as other volunteer-led controls, with consultation with PRISM staff. Basic measurements to assess success include removal, restoration, and adapting responses to predetermined thresholds.

There's a lot of issues associated with invasive species management. Stay tuned for more in the next episode (Part 2).
