Lisa Hill – National Laboratory for Genetic Resources Preservation (USDA-ARS) Drying seeds to appropriate relative humidity is the first step to long term seed storage. NLGRP and CPC recommend drying seeds to 25-35% relative humidity at room temperature. One way to acheive specific relative humidities is to use saturated salt solutions. Here, Lisa shows the […]

Tim Kroessig, Harold L. Lyon Arboretum The Hawaiian flora represents ~45% of all plants listed by the U.S. Fish and Wildlife Service as threatened or endangered. The Lyon Arboretum’s Seed Conservation Laboratory (Lyon S.C.L.) conserves many of these imperiled plants through conventional seed banking. However, the seeds of many rare Hawaiian plants have never been […]

Jim Locklear, Lauritzen Gardens Blowout penstemon (Penstemon haydenii) is a critically imperiled (G1) plant listed as an endangered species by the USFWS. It is presently known from ten occurrences in the Nebraska Sandhills and three in the Ferris Dunes of Wyoming. This species is associated with areas of active wind erosion within a grassland matrix. […]

Germination Testing Program Cheryl Birker, Rancho Santa Ana Botanic Garden The California Seed Bank at Rancho Santa Ana Botanic Garden has a germination testing program to monitor the viability of its many conservation seed collections. Germination tests are conducted on all incoming seed collections before they are placed in freezer storage, and for all rare […]

Assessing Seed Storage Behavior of the Texas Flora to Inform Seed Bank Design

The Botanical Research Institute of Texas (BRIT) is in the process of constructing a seed conservation laboratory and seed bank. While BRIT has been active in conservation for decades and has partnered with regional seed banks to conserve rare species, BRIT has never had a dedicated seed laboratory on site. The goal of the BRIT […]

Special considerations in the seed collections of two NC rare plant species

Recently updated Best Plant Conservation Practices to Support Species Survival in the Wild detail guidelines for seed collection of rare plants. These include multiple aspects to consider in making seed collections regarding target species characteristics, collection timing, seed collection amount, population genetics and maintaining site quality. Here we outline seed collections for two species for […]

Conserving the Alpine: From Tiny Seeds to Big Collaboration

Jennifer Ramp Neale, Denver Botanic Gardens Alpine plants are at risk of population decline and/or extinction due to climate change. Understanding these plants and the environments in which they survive and thrive involves a multi-tiered approach including in-situ and ex-situ efforts. At Denver Botanic Gardens we are working to collect and study seed of alpine […]

All in the family – the case for collecting by maternal lines

Conservation seed collections support species’ survival by acting as an insurance policy in the face of extinction. They can also provide resources for research, restoration and reintroduction. A high-quality conservation seed collection has both depth and breadth – capturing genetic diversity within and geographic diversity among populations. Collecting and storing seeds by maternal line (i.e., […]

Ed Guerrant, Rae Selling Berry Seed Bank Penstemon peckii (G3-S3 Federal SOC) is an Oregon endemic with a relatively compact range in the semi-arid Ponderosa pine forest east of the Cascade Mountains. The vast majority of known populations (ca 93%) are almost entirely within the Sisters Ranger District of the Deschutes National Forest. A 1992 […]

Why Seeds and Spores Die in the Freezer and Sometimes Faster That Anticipated

Chris Walters, Research Leader of the Plant Germplasm Preservation Research team at USDA-ARS National Laboratory for Genetic Resources Preservation Knowing how long storedgermplasmsurvives is critical for effective banking of genetic resources. Longevity is inherently difficult to predict because there are so many factors controlling how cells respond to storage conditions. Uncertainty increases forgermplasmcollections of natural […]

What did we do about our seedbank when Hurricane Irma was due to hit the entire state of Florida?

James Lange and Jennifer Possley, Fairchild Tropical Botanic Garden In the event of a hurricane, low elevation and proximity to the coast place Fairchild at high risk, and thus contingency plans must be in place to preserve our ex situ collections. Anticipating severe damage and extended power loss from Hurricane Irma, we took several measures […]
