Honey bees have fallen on hard times in recent years. A mysterious phenomenon known as “colony collapse disorder,” where worker bees that maintain a hive suddenly disappear, has beekeepers on edge. Bees are also susceptible to all kinds of viruses and mites, not to mention pesticides. But as bee populations have decreased, the demand for locally produced honey has increased. Luckily, a growing group of Philly-based beekeepers is taking care of our local bees.

You can get a look inside the work of these beekeepers this Sunday at the Woodlands Cemetery as part of “Open Apiary Day,” a series of events across the city aimed at familiarizing folks with urban beekeeping.

In West Philly, beekeeper Daniel Duffy will discuss beekeeping at the working hives on the cemetery grounds from 2 p.m. to 4 p.m.

Beekeeping has been intertwined with Philadelphia history since the 18th century. L.L. Langstroth, who is considered the father of modern beekeeping, was a Philadelphia native.

Open Apiary Day events are also taking place in Fairmount/Brewerytown and Mount Airy. The West Philly event includes a tour of the cemetery and arboretum.

Organizers are asking people to RSVP for the free event by calling 215-386-2181 or e-mailing info [at] woodlandsphila.org.

Later this month The Rotunda is hosting a June 23 screening of Queen of the Sun, a film about the disappearance of bees worldwide. The film starts at 7 p.m. and is a fundraiser for the Mariposa Food Co-op expansion.

More details are rolling in about the opening of Clark Park’s “A” section. The June 16 opening ceremony is scheduled to begin at 4 p.m., just after the weekly Thursday farmer’s market kicks off.

The opening will incorporate the market with “A Taste of the Market,” a sampling of products from market vendors.

Deputy Mayor Michael DiBerardinis, state officials and multiple community partners will also be on hand.

It seems like space (or maybe food) is limited for this thing and those interested in attending are asked to RSVP to Barbara McCabe of Philadelphia Parks & Recreation at barbara.mccabe [at] phila.gov or (215) 683-3679.

The northern section of Clark Park (Park A) will officially reopen June 16, according to the Friends of Clark Park website.

An opening ceremony is tentatively scheduled for the afternoon (after 3 p.m., though an exact time is not set) and will include representatives of state and local government, Philadelphia Parks and Recreation, and cooperating partner organizations.

The park has been undergoing major renovations since September 2010, including the removal of several trees. Other changes include paved paths, lighting, drainage and resodding.

The central plaza area of the new “A” section will also include cafe style seating with small tables and chairs. We’re not sure how these are going to be secured. The tables and chairs were bought with a $3000 donation from Bryan and Lisa Hanes.

Landscape crews mowed the newly installed grass at Clark Park “A” today, a major step toward opening the section of the park that borders Baltimore Avenue, which has been fenced off since late last year.

The Friends of Clark Park wrote that one of the “yardsticks” for opening the park was two successful mows of the grass that had been laid down over the last few weeks. The trigger for opening the part will be the next cut. The fencing was scheduled to come down sometime in June. Now we will all be watching for the second cut, which will signal the park’s long-awaited opening.

Saturday is “Love Your Park Day” in Philadelphia. For most of us, I suspect that every day is love your park day, but this one is official. That means that volunteers are needed.

Volunteers are needed at Clark Park from 9 a.m. to 1 p.m. Projects include cleaning the peripheral areas of the park to get them ready for spring and putting mulch around tree bases, beginning with the trees near the shuffleboard court at 45th and Chester. If weather permits, park benches will get a coat of sealant.

Help is also needed at Malcolm X. Park for a general clean-up from 10 a.m. to 1 p.m. and at Barkan Park (50th & Spruce) from 10 a.m. to 12:00 p.m.

Volunteers are also needed at Cedar Park from 10 a.m. to 1 p.m. to help with the park gardens. Bring clippers and cutting shears if you have them. Other tools will be provided.
