Sunday, July 23rd
Conference attendees can begin picking up their registration packets after 3:30 p.m. in the lobby of the Anheuser Busch Natural Resources (ABNR) building (1111 East Rollins Street). Likewise, easels will be available to set up posters and tables for displays and exhibits in the ABNR 123 or the lobby. The NNGA will hold their annual Board of Directors meeting starting at 9:00 a.m. in ABNR 210. The Walnut Council Foundation and Walnut Council will hold their Board of Directors meeting at the Hampton Inn & Suites Columbia at the University of Missouri, 1225 Fellows Place (not the Hampton Inn on 3410 Clark Lane). The Chestnut Growers of America will hold their Board of Directors meeting at 4:00 p.m. in ABNR 210.
A welcome reception with hors d’oeuvres will be held that evening in the ABNR reading room and lobby from 5:00 – 7:00 p.m. The cost of the reception is included in the full and companion registration fee. Following the reception, a poster session will be held from 6:00 to 7:00 p.m. with most presenters by their posters. The member-sharing Show & Tell will follow the reception in ABNR Conservation Hall with 10 minute or less “lightning talks” from 7:10 – 8:30 p.m. This ever-popular event will include presentations from individuals who want to introduce themselves, who have built or tried new equipment or techniques, promising selections or cultivars, had some recent successes or failures.
Monday, July 24th
For most of the attendees, Monday will be an all-day field trip to the Horticulture and Agroforestry Research Farm (HARF; visit moaes.missouri.edu/central-missouriresearch-extension-and-education-center/horticulture-andagroforestry-research-farm for more information) from 8:45 a.m. to 4:30 p.m. Field tours will include the repositories, progeny, and cultivar trials for chestnut, hazelnut, black walnut, and northern pecan; demonstrations of equipment; and how-to videos on grafting and podcasts around the haybarn (pavilion).
Attendees will be asked to carpool or drive their own vehicles to HARF (approximately 45 minutes or 25 miles one-way from campus). There is plenty of parking around the haybarn. A staggered lunch will be served in the pavilion with those going to the alternate timber management field tour served first.
An alternate half day timber management field tour to a nearby woodlands is planned for Monday afternoon for those more interested in forest management than tree improvement and orchard management. Planned topics include controlling invasive species, alternative vegetation to grass, small log utilization, thinning, and an equipment display, including a small sawmill.
Dinner will be on your own coming back from HARF.
Check out the visitcolumbiamo.com website for list of restaurants in Columbia for a quick meal before the start of the evening session at 7:00 p.m.
Monday evening, we will be back on campus. A second poster session is planned from 7:00 to 7:30 p.m. A live auction will follow the poster session starting at 7:30 p.m. All are welcome to attend – bring your checkbook, cash, or credit card! In the past, auction items have included artwork, handmade donations, plant material, nut products, baked goods, and/or gift certificates. Please consider donating items to the live or silent auction regardless of which organization you belong to. If you are an exhibitor, this is an excellent way to advertise your products. Donation forms will be available to indicate whether you prefer silent or live auction and what organization’s research program should benefit from the proceeds. If you donate baked goods, please label your treats as to whether they are nut, dairy, or gluten free.
Tuesday, July 25th
The NNGA and WC will have short business meetings from 7:45 to 8:15 a.m. to set up or complete voting for new officers, directors, committee chairs, or representatives. Coffee will be available in the ABNR lobby before the technical sessions begin.
Tuesday will be the first day of technical presentations starting at 8:20 a.m. and running until 4:50 p.m. The planning committee received an overwhelming response to our call for presentations, so Tuesday’s program will have concurrent sessions with 20-minute talks. One session in Conservation Hall will focus on various aspects of growing and marketing chestnut, hazelnut, pawpaw, persimmon, and pecan. The alternative concurrent session in the Agriculture Sciences Building (700 Hitt Street) will focus more on forest/timber management topics. Both meeting rooms are newly designated as ‘Zoom rooms’ that will allow virtual registration for the keynote and technical presentations for this meeting. A box lunch is included in each full registration.
The silent auction in ABNR 123 will close at the end of the afternoon break. Successful bidders can pay and pick up their items after the last presentations. On Tuesday evening, we will set up for a group photo at 6:30 p.m. in front of the Brewer Field House (1000 Rollins Street) during the cash-bar social from 6:15 to 7:00 p.m. inside the Field House. The annual banquet will start at 7:00 p.m. in the Field House. The cost of the banquet is included in the full and companion registration to encourage everyone to attend.
After we eat, we will have the conference keynote presentation by Shawn Mehlenbacher starting around 8:00 p.m. After the keynote, we will give each organization a little time to entertain us with selection of the new Big Nut, presentation of awards, roll call of states, and announcing results of their annual elections. Wednesday, July 26th Wednesday morning, we will continue with technical presentations in ABNR Conservation Hall on topics we believe will be of interest to members of all hosting organizations. We will ask attendees with poster presentations to leave the posters up for the morning as a concurrent activity to the technical session.
Posters will be set up in the ABNR lobby. Posters should be formatted to fit a 36 x 40-inch poster board set on a two-sided easel. Poster presenters are expected to register for the conference and be present (or have a colleague) by their posters during the two scheduled poster sessions from 6:00-7:00 p.m. on Sunday and from 7:00-7:30 p.m. on Monday.
Exhibits and displays will be in the ABNR lobby or ABNR 123 if they need to locked up when not attended.
Registration for exhibitors includes a table and one full registration to attend all events or choose display or exhibit registration which includes one unattended table without a registration. If you are unable to attend and have a display or exhibit, please call or contact Caroline Todd (email@example.com) to arrange for shipping and setting it up. A ‘staging room’ will be set up inside the Agriculture Sciences Building (700 Hitt Street). Use the city’s metered parking (quarters or credit card) along Hitt Street while loading and unloading vehicles.
Please plan to donate items to the live and/or silent auctions that will be conducted to support the NNGA and WC Foundation research grant programs. The NNGA/CGA will host a live auction on Monday evening. The Walnut Council Foundation, the educational arm of the Walnut Council, will set up a silent auction that will be open from Sunday evening and run through the break on Tuesday afternoon. Be sure to complete the donation sheet that will be printed in the summer issue of The Nutshell or at the door so we know your preference as to live or silent auction, distribution of proceeds, and if you have a reserved bid.
On Tuesday, an alternative program is being arranged for those who do not register for the technical sessions.
Participants on the Companion (or CAPS) program will tour several local sites which are still being arranged and
enjoy lunch together. The meeting place will be announced at the Sunday Show and Tell.
Sunday’s welcome reception, Monday’s field tour lunch, Tuesday box lunch and breaks, Wednesday’s breaks, and Tuesday’s Social/Banquet are included in the registration fee. Other meals are on your own. The Plaza 900 cafeteria (900 Virginia Avenue) will be open for breakfast ($10), lunch ($12), and dinner ($12). Payment must be by credit card. The Student Center (901 E. Rollins Street) one block from the conference venue has a cafeteria as well as a gift shop and bookstore. The downtown area has numerous local restaurants within a five-block walk
Campus housing will be in the College Avenue residence halls (1300 Rollins Street) accessible off Rollins Street.
Single rooms with one twin bed and double rooms with two twin beds are available for $180 and $200 ($100 per person) for a Sunday, Monday, and Tuesday night stay that includes linens and towels. If you need Saturday or Wednesday night, call Caroline Todd (573-884-2874).
Rooms have both Wi-Fi and air conditioning. Each room shares a common bathroom with another room. Housing reservations need to made by May 21 and paid for on the registration form. After May 21, call Caroline Todd (573-884-2874) to see what is available. Fifty percent of the housing fee will be refunded if cancelled 10 to 60 days before the conference.
For those staying in the College Avenue campus housing, plan to use the parking behind the residence hall and Bingham Commons. The least expensive option for parking is to purchase a 7-day pass for $24 that allows you to park in the lot behind the residence hall and the Hitt Street Parking Structure (metered parking is not included). There is a pedestrian overpass over College Avenue that leads to the Plaza 900 cafeteria and Virginia Avenue to conference area. Golf carts will be available to help those with limited mobility move between the residence hall and ABNR on campus.
Because the University is between sessions, there should be plenty of parking near the conference area. You are encouraged to park along Hitt Street during the day and feed the meters with quarters or credit card or keep it simple and purchase a 7-day pass for $24 to park in the Hitt Street Parking Structure (309 Hitt Street) any time day or night. We will have golf carts shuttling people between the parking garage and ABNR.
If you have an ADA placard or license plates, you can park first come/first serve in any non-reserved and non-restricted accessibility spaces on campus including the Hitt Street Visitor Lot (HSVL) across the street from the Agriculture Sciences Building with the purchase of a $24 7-day pass.
We have booked a block of rooms with discounted rates as an alternative to the residence hall. The Hampton Inn and Suites Columbia at the University of Missouri, 1225 Fellows Place (not 3410 Clark Lane) is approximately 0.5 miles south of the campus. Regardless of which organization you are a member of, call 573-214-2222 to book at the special “Walnut Council” group rate of $115 + tax per night or book online at bit.ly/3jIBuXc. This includes a free hot breakfast and free parking. Pets are allowed with an additional one-time charge of $50 for up to 4 days. Consider walking between the Hampton Inn and ABNR or the Brewer Field House to avoid purchasing a 7-day pass or feeding meters.
On Sunday, the Board of Directors meetings for the Walnut Council Foundation and Walnut Council will be held in the Hampton Inn meeting room.

There is plenty of parking at the Horticulture and Agroforestry Research Farm (10 Research Center Road, New Franklin) by the haybarn (pavilion) surrounded by a gravel parking lot and along the roads on the farm. Directions from Columbia to HARF (that avoid the US-40 road closure between Hwy 240 and Hwy 5) involve taking I-70 W to US40 W (exit 121) to MO-240 W (toward
Fayette) to State Route P south into New Franklin. Alternatively, take I-70 W to MO 87 (exit 106) toward Boonville to Hwy 5 and follow Hwy 5 north through Booneville past the casino and into New Franklin. Once in New Franklin, stay on Broadway (Hwy 5) past the school, turn left on Research Road just before the New Franklin Car Wash. After the curve, HARF will be on the right.
Follow the gravel road for approximately one mile past the HARF shade house and office to the hay barn (pavilion).
The field tours will start with a welcome at 8:45 a.m. and run through 4:30 p.m. We will use bleacher wagons (capacity 30 to 45 people) for the near and far-loop tours. A walking tour is planned for the field stops around the haybarn and demonstration area. All three tours are scheduled to be repeated two times. Stops are scheduled for most of the repositories, progeny, and cultivar trials for chestnut, hazelnut, black walnut, and northern pecan.
Equipment planned for the demonstration area include irrigation, electric deer fence, and nut harvesting. How-to videos for topics such as grafting that we cannot demonstrate in the summer will be shown in the haybarn.
After lunch, you will need to decide whether to take the other two field tours at HARF or travel to the alternate timber management field tour at a private woodlot (301 North Highway UU – 1 mile south on UU of eastbound US 40 at I-70 Exit 121). Various field stops are planned to discuss vegetation management, sawmilling and small log utilization, thinning, and an equipment display.
We are trying to set up a few post conference tours you could participate in after the conference on Wednesday afternoon or Thursday morning. Mark your interest on the back of the registration form. If there is no demand, we will not plan those tours.
