The Announcements Forum is a platform-wide channel for announcing plant conservation news such as posting job postings, project news, upcoming conferences/workshops updates. Users are welcome to ask follow up questions on announcements, however, questions related to specific conservation topics should be posted within topic-specific boards. The CPC National Office will use this forum as a primary channel for making program announcements - so make sure your conservation officers are signed up!!

Conventional seed banking (Part 1 of the Best Practice Guidelines) outlines ex situ conservation actions for seeds of species that are capable of being stored at freezing temperatures. Users are welcome to ask questions about this section & seed baking in general, share news & knowledge about seed banking from their institution, and comment on Frequently Asked Questions generated by CPC about conventional seed banking.

Alternatives to conventional seed banking (Part 2 of the Best Practice Guidelines) describes the special handling and options available for species that have seeds that cannot withstand desiccation and freezing. These options include "living collections" of plants in field genebanks, conservation groves, inter-situ collection, tissue culture and cryopreservation. Users are welcome to ask questions about this section & exception species curation in general, and share news & knowledge about this topic from their institution.

Genetic considerations for plant conservation (Part 3 of the Best Practice Guidelines) provides guidance for maximizing genetic diversity when collecting, maintaining, and reintroducing rare plant species to the wild. Users are welcome to ask questions about this section & genetic methods in general and share news & knowledge about genetic research from their institution.

Rare plant reintroduction and Other Conservation Translocations (Part 4 of the Best Practice Guidelines) describes the framework for conservation actions that can improve the chance of successful rare plant reintroductions to the wild. Users are welcome to ask questions about this section & reintroduction in general and share news & knowledge about reintroductions conducted by their institution.

Documentation and Data Sharing (Part 5 of the Best Practice Guidelines) describes the type and format of documentation that comprise best practices needed to ensure the possibility for universal sharing of seed collection, propagation, and reintroduction data. Users are welcome to ask questions about this section & data sharing in general and share news & knowledge about data sharing conducted by their institution.

The curation value of seed banking relies on our ability germinate and propagate plants in collection. Germination Testing & Propagation does not currently have an associated section in the CPC best practices but discourse from this forum will help inform what topics and authors that should be involved in this future guidelines. 

Habitat loss and degredation is a significant threat to plant diversity globally.  Managing threats, such as invasive species, agricultural land use, and recreational activities, and restoring native habitat are critical to the long term survival of rare plant species. Land Management does not currently have an associated section in the CPC best practices but discourse from this forum will help inform what topics and authors that should be involved in this future guidelines. 

Accurately assessing the population status of species in the wild (in-situ) is the primary way plant conservationists identify species in need of ex-situ curation in botanical garden. Plant Monitoring and Demography does not currently have an associated section in the CPC best practices but discourse from this forum will help inform what topics and authors that should be involved in this future guidelines.

Specific funding sources for rare plant conservation may vary greatly by region, taxon, and year. In the video link below, Mary Pfaffko from the Georgia Department of Natural Resources describes sources and strategies for securing rare plant conservation funding in Georgia, which may have parallels to other states and regions.

We had a potential project with salvaging Rotala ramosior (annual) pop up and we are hoping to quickly find information on this plant so we can advise/store properly. Has anyone worked with this species (or genus) before? A wetland annual plant, we are hoping to know about when best to collect, how best to prep and store, both long- and short-term, and how to best maximize germination. Any experiences working with this species would be most welcome.

  BGCI-US and the Montgomery Botanical Center present findings of a 3-year, multi-institutional project to find the most effective ways to capture, steward and sustain plant diversity in botanic gardens. This 12-page guide summarizes the results and lessons learned from intensive review and novel genetic studies of this fundamental need.

Hi CPCers,

Please share your examples. At The Arboretum at Flagstaff our garden soil was volcanic, but we had many rare species that required limestone soil.  We created a limestone mound along a planned garden path to support several rare limestone species in the region.

Looking at the types of horticulture practice that we may want to present in the Horticulture best practices in the Propagation sub-section, we plan to have seed, cuttings, propagating from division and we could have grafting or layering.  Is the latter used for rare plants?  Can you please share your examples?

Hi, all.  We are going to be doing tetrazolium testing for viability with Apios priceana and Physaria globosa in the near future. However, I am finding it difficult to acquire full procedures for tetrazolium tests that are genera or family specific. I did find a PDF for one of the three published procedures for plants in the Fabaceae from the Association of Seed Analysts, but am unsure if it is the right one. I have yet to find access to any protocols for seeds from plants in the Brassicaceae.

On my profile, the best practice sections I've authored show up under both the "contributed videos" and "best practices" (This is also a test to see if the links to the discussion boards are now working)

Our summer fellow pointed me in the direction of this interactive platform for seed germination analysis. I can see it being a useful instrument for producing visualizations for reports if can make the fields fit your needs.

We have used both foil and plastic vacuum sealed pouches for packaging glassine envelopes prior to storage in the seed bank freezer. Are there major advantages to foil vs. plastic? We have used foil historically, but have also used plastic. The benefits to plastic that I see are not just that it is cheaper, but also that you can customize the size of your pouch more easily. Sometimes we have a very small collection and don't need a full foil pouch and sometimes if we have bulky seeds, it's helpful to make a slightly bigger pouch.

Our group is considering writing a proposal to test the soil seed bank of an endangered annual (Acanthomintha ilicifolia). There are several clay lenses that this species was previously found to inhabit, but it has not been observed aboveground for many years, and other populations are contracting. We are debating how many samples to take and at what interval across space we should take them across the suspected habitat. Does anyone have suggestions from experience or know of specific papers that relate to this type of sampling?

I cannot seem to be able to answer questions in the Forum without first clicking on the "Save" button (i.e. with no answer text), then using "Edit" to actually enter the answer text. I found I have the same issue with creating a new post - such as this issue note. Please advise - Thanks!

I visited NLGRP in Fort Collins this week, and they showed me their new microscope software (for their Keyence microscope) that had lots of fun bells and whistles including software that has promise for counting seeds and pollen through the microscope. Does anyone currently use digitial seed counting as part of their currently seed bank methodology? I'm mostly curious if anyone has worked through all the hiccups and actually put it into practice.
