Monthly Summary Bee Activity Index

Monthly Summary Bee Activity Index

The Bee Activity Index is published on the website daily for the previous day and it also summarized here on a monthly basis. Our Bee Activity Index is based on our weather information and our close range photogrammetry at the beehive entrances. The larger the number the greater the potential bee activity as controlled by meteorological conditions.

Precipitation vs. Evapotranspiration

Monthly Precipitation vs. Evapotranspiration:

This chart shows the amount of precipitation (moisture incoming) to evapotranspiration (moisture outgoing) plotted on a daily basis for the month. If the evapotranspiration exceeds the precipitation value it indicates a negative moisture balance which can effect nectar flow and perhaps the need to provide water to hives.At Black Birch Farm Apiaries we monitor Soil Moisture, Precipitation, and Evapotranspiration to determine moisture stress on both hive activity and nectar flow.

Cumulative Precipitation vs. Evapotranspiration

Monthly Cumulative Precipitatiom vs. Evapotranspiration:

This chart shows the cumulative amount of precipitation (moisture incoming) to evapotranspiration (moisture outgoing) plotted on a daily basis for the month. If the evapotranspiration exceeds the precipitation value it indicates a negative moisture balance which can effect nectar flow and perhaps the need to provide water to hives.At Black Birch Farm Apiaries we monitor Soil Moisture, Precipitation, and Evapotranspiration to determine moisture stress on both hive activity and nectar flow.

Monthly Soil Moisture and Drought Monitoring

Monthly Soil Moisture and Drought Monitoring:

At Black Birch Farm Apiaries we monitor Soil Moisture, Precipitation, and Evapotranspiration to determine moisture stress on both hive activity and nectar flow. This information is posted on a monthly basis. Note: During winter months select data is unavailable

Legend (BBF = Black Birch Farm):

Blue = BBF DEW POINT (Wetness in Degrees Fahrenheit)

Red = BBF SOIL MOISTURE (Water Content in m3/m3)

Orange = BBF REFERENCE EVAPOTRANSPORATION (Reference ET in Inches)

Black = BBF RAINFALL (Total Rain in Inches)

Green (May be absent from chart) = BBF LEAF WETNESS (Wetness in Percents)

2023 BEE SEASON - GROWING DEGREES DAYS (GDD)

AVAILABLE ON OUR SEASONAL REPORTING PAGE

2023 Bee Season - Growing Degree Days (GDD):

At Black Birch Farm Apiaries we monitor Temperature, Rainfall, Cumulative Precipitation & Evapotranspiration to determine moisture stress to determine Growing Degree Days (GDD) and their affect on both hive activity and nectar flow. This information is posted on a seasonal basis. Note: During winter months select data is unavailable.
