Rangeland specialist Jim Clawson first initiated the forage production data collection at UC SFREC in 1979. Past Director Mike Connor expanded the process with monthly (rather than seasonal) sampling of the usable forage in a particular area. Three plots were originally set aside to sample, but following multiple trials one specific plot was chosen. The same 1-acre grazed plot has been used for the past 35 years, as it is located at a median elevation with moderate canopy cover and a fairly representative soil of the entire ranch.
This year's forage production data was rather interesting. Late fall rains followed by freezing temperatures during germination, coupled with the severe winter drought, created dismal forage growth at the beginning of the yearly cycle (typically starting in December). However, the heavy rainfall experienced at the end of January and in the following months proved sufficient enough to produce nearly 80% of average forage production. As the person who has taken responsibility for keeping track of the forage production measurements and compilation, UC SFREC Superintendent Dustin Flavell has noticed an interesting trend; the total amount of precipitation is not always strictly correlated with the total pounds of forage produced per acre. “The right amount [of rainfall] at the right time and frequency will result in the most growth,” said Flavell.
Producers may find it useful to monitor forage production and peak standing crop on their own ranches. While there are varying definitions of peak standing crop, at UC SFREC it is measured when a majority of the grasses begin to cure but do not reach full maturity (seeds ready for dispersal). Peak standing crop typically occurs early to mid May. Several publications are available from the research conducted on forage production and residual dry matter that go into more depth about the importance of monitoring grass growth. One particular publication offers a simple 6-step method for determining forage in pounds per acre.
With a new growing season just around the corner, be on the lookout for additional posts regarding forage production at UC SFREC.

Peak standing crop at SFREC for the 2013-2014 forage production year occurred on May 20, 2014 and yielded 2300 pounds per acre for the season. This is 77% of the historic average of 2971 pounds per acre. Ending the forage production season at 77% of average is better than originally predicted, considering the cold, dry fall and early winter , along with the historic low forage production through January.
Precipitation totals for the season came to 16.63 inches which is 56% of the historic average of 29.5 inches annually. Considering we received 12.5 inches of rain from February to May further shows that rain during the rapid forage growth season means more to overall forage growth than total precipitation. In fact, had we not had the very cold early December temperatures that immediately followed the 2.26 inches of precipitation at the end of November this forage season would have looked altogether different. Starting the rapid forage growth season at 98 lbs per acre instead of closer to our average of 515 pounds per acre is what most likely kept this from being closer to or better than an average forage season.

This past Saturday, February 22nd, SFREC hosted a forum focused on the future of farming and ranching in the Sierra foothills.
About sixty members of surrounding communities in Nevada, Placer, Yuba, and Sutter counties made it out to UC SFREC for a day of learning, interaction with professionals, and networking. For the vast majority of the attendees, this was their first introduction to SFREC and the UC Research and Extension Center system.
The speakers offered insightful and useful information that engaged the entire audience. Jamie Johansson, Second Vice President of the California Farm Bureau and owner of Lodestar Farms, kick started the conversations by speaking about the opportunities and challenges of farming in the foothills. Dan Macon, representing Placer County UCCE and Flying Mule Farm, offered logical business planning strategies from a personal and professional perspective.
A significant aspect of this event focused on incorporating local youth. We were able to help partner students from high schools in the region with a few of the producer-presenters prior to the forum. This additional opportunity enabled a more profound learning experience for students interested in the future of farming and ranching.
There was a DELICIOUS locally sourced lunch with juicy tri-trip, salads, bread, and lavender sweets. Briar Patch co-op in Grass Valley also donated coffee and pastries for the event. Local ag and natural resource conservation groups brought educational materials to share. Attendees enjoyed the beautiful weather and slowly greening rangeland on a brief tour of the center.
Overall, it was a successful event that kindled connections with the community and opened the door for future cooperative efforts.

On February 22nd, community members, local farmers and ranchers, professionals, high school students, non-profit groups, and regional leaders in the ag industry will be gathering in Browns Valley for a forum on The Future of Farming and Ranching in the Sierra Foothills. This event has been in the making since summer when committee members helped lay the foundation for a useful and exciting day about the opportunities and challenges of agriculture in this region.
Speakers will be sharing their personal experiences and knowledge about getting started in agriculture and reaching goals. Topics about resources needed, tools available, and strategies to stay in business will be discussed. High school ag students will present information learned from visits with local farms/ranches and other important areas researched. Multiple non-profit groups will be displaying information and resources as well. There will be a delicious lunch, sourced from local farmers and ranchers (some of which will be present). The cost to attend is $10 per family. Register through our website at http://sfrec.ucanr.edu/

Forage growth through the end of January at SFREC set an all-time low of 98 pounds per acre. Typically we should be around 515 pounds per acre this time of year. Forage composition is also leaning pretty heavily towards broad leaf species like filaree which can dry up pretty quick. The chances of having an average or above average forage year this season seems highly unlikely based on history, but there is still hope to have a decent below average year. In the 1990-91 forage production year forage production values through February indicated 162 pounds per ac and we reached 2,565 pounds per ac at peak standing crop, which was 86% of average, this was the year of the "Miracle March”.
Making the forage year look more optimistic, SFREC received over 5 inches of rain over the weekend brining our totals up to about 9.3 inches. While we should normally be around 17 inches this time of year it is a big step in the right direction.
