What is the Seed Sourcing Grant?

The use of farm saved seed FSS carries unnecessary risk for farmers. Certified Seed is the cornerstone of many farming operations and various food and beverage industries. The cost of certified seed includes a full rate contribution to plant breeders ensuring development of new varieties for the future.

Importing or Buying Imported Certified Cereal Seed If you look at importing seed or buying imported seed, you should be aware of the standards of certified seed in the country of origin. Irish certified seed has a voluntary zero tolerance for several invasive weeds that may have a tolerance level in other countries.

Home saving imported seed increases the associated risks. Farm Saving Seed If you choose to save your own seed you should be aware of seed health and risks and you should closely monitor and control weeds in seed and crops that may spread from your fields to others.

Further information on farm saving seed is available by reading the rates and processing sections. Please note that PVDO will audit annually a number of farmers to ensure they have either declared use of their own Farm Saved Seed or have proof of use of certified seed.

To plant resilient woodlands, we need to ensure supplies of genetically diverse tree seed of known origin are available from a range of seed provenances. We also need to make sure we have a diverse range of species including both natives and future alternative species.

This poses a significant challenge, especially whilst trying to minimise imports to reduce the risk of introducing harmful pests and pathogens into the UK. Through the Nature for Climate Fund NCF Sector Capacity Project, we are working to increase the quality, quantity, and diversity of Seed Stands and Orchards across England.

That means encouraging the development and planting of new Seed Stands and Orchards. It is also about supporting the identification, registration and management of existing Stands and Orchards to ensure they are accessible and productive for seed collections.

The Seed Sourcing Grant SSG first opened in September , and again in May , to provide funding to create or identify Seed Stands and Seed Orchards, and also make existing stands as productive as possible for seed collectors. For this round, we have reduced the minimum grant spend to £2, to encourage those with smaller projects to apply for the funding.

For example, if you have an existing piece of woodland that you think would make a good Seed Stand then funding could support work such as fencing, thinning or access improvements, to make it more productive for seed collections.

As well as the SSG, we are re-opening the Tree Production Capital Grant which supports nurseries and seed suppliers through investments in equipment and facilities, such as seed storage facilities. The FRM system and seed sourcing can be a complicated topic. The very minimum number of trees required for a Source- identified Seed Stand would be 30 for a monoecious species both sexes per tree or 60 for a diecious species separate male and female trees.

In either case, these trees would be seed bearing age and good form. However, applications are looked at on a site-by-site basis and the FRM team would usually expect there to be at least trees, especially for a Selected Stand.

Trees can be thinned or selectively felled. this means they can keep the National Register up to date. A stand can also be registered temporarily to allow seed collection to be carried out during clear-felling of trees for harvesting.

Note that felling licensing regulations apply. Their details will then appear on the far right of the screen. No, they must be registered suppliers and get permission from the landowner or agent of the site before starting any work.

If you are proposing to register a Selected Stand or a Seed Orchard, there will need to be an inspection carried out by Forestry Commission prior to registration. This will look at certain criteria, e. location and isolation, size of population and uniformity.

However, it is unlikely that Source-identified stands will need to be inspected unless they are identified as indigenous. Trees are long-lived individuals and produce significant numbers of seeds.

Therefore, taking a greater proportion of seed available is unlikely to be damaging to natural regeneration especially if collections are not made every year. However, to allow natural regeneration of the stand and to capture the maximum genetic diversity in your seed collection, it is always better to collect fewer seeds from the greatest possible number of individuals rather than collecting all the seed from a small number of individuals.

Tree Production Capital Grant webinar, Wednesday 10 January With the third round of the Tree Production Capital Grant now open, this webinar will offer advice about applying and an opportunity to ask any questions.

The Tree Production Capital Grant provides funding to increase domestic production of tree seed and saplings, supporting investments in expansion, automation and mechanisation of facilities and equipment.

Register to book your place. Join the Forestry Commission to learn more about the third round of the Seed Sourcing Grant funding. The grant team will guide you through applying, and there will be time for questions. The Seed Sourcing Grant is designed to improve the quantity, quality and diversity of tree seed sources in England.

This will support availability of planting stock to meet tree planting needs and boost domestic tree seed production. So far, 14 projects have been awarded funding through the SSG.

For example, Clive Ellis applied to put in place management of compartments of an Ancient Semi-Natural Woodland to enhance seed production in a small leaved lime stand. Megan and her team deliver four grants funded by the Nature for Climate Fund: the Seed Sourcing Grant, Tree Production Capital Grant, Tree Production Innovation Fund and Woods into Management Forestry Innovation Funds.

Seed sourcing and quality control -

Notified seed inspectors inspect the seed selling points to verify the quality of the seeds. They also draw seed samples when they suspect the quality of the seeds being sold. Seeds are then, sent to Seed Testing Laboratories for analysis. Legal actions are initiated against the defaulters based on the analytical results.

Seed selling licenses are issued under Seed Control Order Seed Inspectors also take appropriate action as and when complaints are received from farmers. Role of farmers in maintaining the quality of seeds Farmers should purchase the seeds only in the licensed seed selling points.

Verify the details furnished in the producers label attached to the seed bag. The label should possess the following details SL. Crop Variety Lot No. When the farmers suspect the quality, they should report the matter to the concerned seed Inspector. Further they should keep with them the tag, label and the container of the seed bag.

If the seeds do not germinate properly, the fact should be reported to the seed inspector concerned. Whenever the farmers purchase seeds they should verify the variety and its performance. They should avoid purchasing un notified varieties.

The farmers should obtain receipt for the purchase of seeds without fail. In the receipt, details on variety, Lot number and validity period should be verified at the time of purchase. List several grassland organizations and describe their role in promoting forages and grassland agriculture.

We recognize that the question we posed is likely too broad. Seed sourcing in an era of climate change is incredibly complex.

If we had conducted a more focused search on a particular region or community type, e. But climate change provides an existential challenge that has been broadly addressed by research for many decades. Therefore, we are surprised by the lack of data with which to undertake any meta-analysis, even for well-studied forest trees.

This was largely driven by the high number of response variables we encountered. We recorded a total of unique response variables, and while we were able to place them into broad categories, there was no single category that provided sufficient data for a meta-analysis.

Many studies did use survivorship as a response variable, but the life stage at which they measured survivorship was also highly variable, making direct comparisons difficult. Another response variable we encountered with high frequency was plant height. While plant height has successfully been used in autecological and demographic studies, comparison across multiple unrelated species with a diversity of life histories, e.

A common set of parameters established for use in evaluating plant performance from an ecological perspective, across climate gradients, or climate proxies would provide the foundation for powerful analysis in future work. We anticipated that we would discover general trends in plant performance across a gradient of environmental conditions that would prove useful for seed sourcing decisions for restoration practitioners.

We found that trees, particularly those species that have economic value, are well-represented by provenance studies in the literature. Developing an aggregated database for these species might provide useful data for meta-analysis.

In light of these findings, we have several recommendations that might bridge the gap between study and practice. Source Identified Seed. It can be a challenge to find sufficient quantities of seed with the collection origin and the production data readily available.

Moreover, a central database of seed origin and availability would make seed purchases easier and could be a tool for the industry for tracking demand e. In addition, documenting the outcome of on-the-ground restoration projects using source-identified seed would provide valuable insights into plant performance from different sources.

Species Distribution Modeling SDM. Ramalho et al. The approach they outlined included the use of user-friendly internet resources that could be implemented by practitioners to choose source locations beyond their typical protocols.

A similar approach was recently implemented by McKone and Hernández in a prairie planting in Minnesota, United States. However, they advocate the introduction of species that might naturally expand their range, as predicted by models of climate-based range envelopes, rather than sourcing ecotypes of species outside their local region.

Another approach taken by one of the authors here P. Vitt involved the installation of an experimental seed mix design utilizing the species palette typical for de novo prairie restorations but sourced using SDM-based climate envelopes Figure 1B.

Exploratory modeling was undertaken using the tools presented by Ramalho et al. The results were used to set the source specifications for seed purchased through a standardized competitive bidding process. The experimental planting was paired with the same suite of species sourced in a similar bidding process specifying the seed origin as outlined in Figure 1A.

The first seeding was implemented in February but failed because of a prolonged and deep regional drought. A second seeding was installed in February No data are yet available.

Regional Seed Networks. We know of several efforts to develop appropriate native seed supply regionally, including the Colorado Plateau Native Plant Program United States , the Nevada Native Seed Partnership United States , Northern Illinois Native Seed Network United States , Ontario Plant Restoration Alliance Canada , Southern Alberta Native Seed Collaborative Canada , and the Xingu Native Seed Network Brazil.

Networks of all sizes can help ensure the availability of native seed through cooperative collection and production, and they can provide feedback on the performance of seed across regional restoration projects. Efforts such as these can help expand the availability and use of source-identified seed.

We advocate for the creation of more such networks. Dynamic Seed Transfer Zones. Seed transfer zones are spatially explicit regions within which plant material may be moved while also minimizing the loss of fitness via maladaptation as well as avoiding the disruption of population genetic patterns.

We recommend developing regional spatiotemporal seed transfer zones Marinoni et al. Increased integration between practice and theory. When researchers and practitioners work collaboratively on restoration projects, the results may prove particularly insightful Dickens and Suding, ; Jellinek et al.

Many studies have focused on extending basic ecological concepts to the practice of restoration Dickens and Suding, , but many of these are done in plot-based experiments that may or may not be correlated with patterns and dynamics at play in at-scale restoration projects.

This science-practice gap exacerbates the uncertainties facing practitioners attempting future-forward climate resilient restoration. Many of the recommendations listed here will be most informative if applied in at-scale experiments done in collaboration.

For example, the long-term resiliency of restored populations may be addressed by a regional collection approach that ensures a diversity of genotypes are introduced to restoration sites Saari and Glisson, ; Herman et al.

More powerfully, purposefully moving populations beyond their current range predictive provenancing to be proactive in response to climate change Havens et al. Either way, addressing these questions within the context of real-world restoration projects would be tremendously informative. Addressing research needs.

Havens et al. US National Seed Strategy. For example, screening multiple sources for the best fit or broadest adaptive potential Leger et al. We call for funding to support long-term studies which are extremely important for ecology in general, and for understanding the impacts of climate change in particular Kuebbing et al.

Also, we advocate for a generalized set of response variables to be used in this type of study see Supplementary Table 2 , to contribute to a unified understanding of the impacts of climate change on plant populations, and implications for seed sourcing.

Furthermore, while many studies that we reviewed focused on height and biomass production as response variables, only a few focused on the reproductive traits of herbaceous perennials such as seed production, viability, germination, etc. However, as reproductive traits are key to understanding restoration outcomes in the long term, and are often uncorrelated to vegetative traits e.

Additionally, we found that most studies only consider a single taxon, while the expectation is that climate change is likely to change community composition.

Therefore, research that addresses how community dynamics might be influenced by seed sourcing should also be undertaken. Finally, we recommend that researchers and practitioners alike consider depositing data and lessons learned with a Restoration Project Clearinghouse to communicate how plantings undertaken with different seed designs are faring over time Havens et al.

Many seeding experiments are undertaken on a small scale, or as part of an on-the-ground restoration project. Data collected by land managers, while an important part of project monitoring, may be informal or accomplished across sporadic timeframes, which may be difficult to analyze.

In combination with the results of formal monitoring however, these observations, as well as data from failed experiments many of which do not get published would provide a more comprehensive and deepened understanding of the processes at work.

It may be necessary to develop an incentive to encourage land managers to spend the time submitting the necessary data through adding such requirements to grants or other funding opportunities. One approach is that taken by the Chicago Wilderness , an alliance of regional land management, academic and private organizations working to advocate for nature in a highly developed landscape.

Their Excellence in Ecological Restoration Program www. The process of the program includes a site visit by a commission of regional professionals who evaluate the work during an extended site visit. These types of interactions provide a critical opportunity for discourse and information exchange.

Although many of the actions that we are calling for here are not new, perhaps there is a greater urgency for implementation.

We are nearing the threshold for important climate change tipping points and the need for tools to ensure climate resilient restoration has never been more urgent. All authors conceived and designed the research and collected data. JF led the data analysis and visualization.
