Once established, however, population dynamics of longer-lived species may be buffered against climate change, relative to short-lived ones Morris et al. Figure 1 Seed procurement specifications from Lake County Forest Preserve District LCFPDIllinois, USA.

A Standard seed sourcing specification used during the bidding process is biased for seed regionally produced south of Lake County, Illinois which is indicated by the map centroid. The District has a two-tier seed provenance system for purchase consideration of native plant material.

Seed sourced by vendors from Tier 1 - Deep Red is given priority over seed sourced from Tier 2 Light Red during purchasing decisions. B Lake County Forest Preserve District has undertaken a test of climate predictive provenancing, with updated Tiers 1 and 2 that were determined by applying Species Distribution Models of multiple species used in standard restoration of abandoned agricultural lands.

Overlapping regions between the standard seed provenance A and the predictive provenance are cut out. We wanted to determine how sourcing decisions under climate change are likely to alter the performance of seed during the establishment phase of a restoration, as well as during later stages when community composition and structure may overshadow the effects of the population dynamics of individual species.

We also wanted to explore if any performance or fitness patterns could be discerned from the literature that might inform the development of specific recommendations for sourcing seed that would provide more predictable outcomes as the climate changes.

We were particularly interested in summarizing the literature around climate resilient seed sourcing so that we could make specific recommendations for land managers and other practitioners that go beyond provisional seed transfer zones Bower et al.

We conducted a review of the literature for studies that had explicit or potential application for seed sourcing under climate change. We sought out experimental studies that assessed differences in performance of plants collected from different populations, i. We had five primary objectives for this review of the literature.

We sought to determine:. The range of species commonly included in these studies, as well as their life histories e. The context in which these studies had been conducted e.

The experimental design of these studies, including the types of experiments used e. In addition, we were interested in how researchers addressed the effects of climate change e.

The motivation for the studies e. We were also interested in determining which funding sources supported the work. As a practical synthesis and application of the above objectives, we wanted to use our review of the literature to understand - and work towards bridging - the gap between the research regarding how plants respond to climate change and the practice of sourcing seed for restoration.

To this end, we provide recommendations in the Discussion. To understand the current state of the science with regard to seed sourcing under climate change, we performed a comprehensive review of the literature and subsequent analysis.

We utilized the available tools to ensure that no reviewer was able to see the recommendations or comments of any other reviewer i. Each title and abstract of the remaining references were reviewed by at least two randomly assigned reviewers to determine relevance to our primary question of seed sourcing under climate change; a subset was reviewed by more than two of the authors because of the blind anonymous review process.

Of the papers thus evaluated, were considered germane by all reviewers, while titles were excluded by all reviewers. One hundred seventy-three titles required further review of the full text to determine relevance and the reviewers were conflicted on the remaining titles.

To reconcile conflicts among reviewers with regards to these titles, two additional reviewers conducted a subsequent blind review of these titles and their abstracts to determine if the studies were relevant. Ultimately, references were determined to be relevant to our question about seed sourcing under climate change and were included in the next step of the review Figure 2.

Figure 2 Process flow diagram illustrating literature search, review, and characterization of studies. Of the articles that were deemed relevant, further review of the abstracts and methods revealed that 63 were reviews of the issues or otherwise provided background information important to consideration of our topic, and 13 were papers that used modeling approaches.

Therefore, a total of papers appeared to be experiments related to provenance testing using reciprocal transplants, common garden studies, or other field-based or greenhouse trials designed to determine how the origin of a seed collection performs in an environment outside of the one in which it naturally occurs Figure 2.

Each of the papers was randomly assigned to one reviewer, who undertook an initial screening to determine if the paper met the following criteria: An experimental study regarding the performance or fitness of more than one origin or source of plant materiali.

Data collection on the included papers was iterative and took place in two phases. To assist our evaluations, we developed a rubric for terminology that was applied inconsistently across the literature we reviewed.

Maternal effects were constrained to papers in which individual maternal lines e. To account for plasticity, an experiment needed to assess at least half-sib families and to follow clones or siblings in multiple environments so that a single genetic signature could be followed and measured with replication.

Lastly, an experimental design that assessed heritability would require full sibs to be evaluated as well as measurements to be taken across different environments to determine the breadth of the expression of the genotype-by-environment interaction.

Table 1 Terms or concepts considered during the review, with their associated multiple-choice responses. Although many studies acknowledged that genetic factors such as plasticity or heritability are important to consider, not all were specifically designed to account for them.

To evaluate this discrepancy, we assessed papers that were experimental papers relevant to our research questions see Results below. We were also interested in establishing if these effects were explicitly integrated into the experimental design and analysis i. We determined whether the experimental design tested the effect of the source climate climate where provenance was collected on trait expression using one of the following variables: proxies for climate e.

If the experiment was determined to have tested the effect of source climate, reviewers listed the traits that varied significantly by source climate, including traits that varied significantly as an interaction with another model term.

To further refine the geographic range of the studies represented in the literature, reviewers indicated the identity of the country or countries in which experiments took place.

Lastly, we compiled sources of funding listed in the acknowledgments. Each funding source was then categorized as follows: federal or national funding e. We used the R environment for statistical computing, version 4.

Visualizations were created with the following packages: forcats Wickham,ggfittext Wilkins, aggmosaic Jeppson et al. Of the papers screened through the literature review process, were excluded during the data collection phase. These included 35 experimental papers that did not address our research questions, 42 modeling papers, 19 review papers, 18 opinion and perspective papers, and 5 methods papers.

Five papers were excluded for miscellaneous reasons - e. One hundred and seventy-six studies were experimental papers relevant to our research questions and are included in the results. The number of studies on perennial herbaceous species, including grasses and forbs, also began to increase around the same time, but remains outpaced by published studies on tree species.

Additionally, the length of time devoted to tree trials is much longer than for other growth forms Figure 4A. Similarly plants with longer life histories, including woody perennials, have been studied more intensively than annual or biannual plants, Figure 4B.

The bias towards tree species is also reflected in the frequency with which journal titles were observed, as Forest Ecology and Management was the most frequently observed Supplementary Figure S2. While the most-represented journals were tree centric, the journal Evolutionary Applicationswhich has a broader scope beyond forestry, was also frequently encountered among the papers we reviewed.

Furthermore, while there were approximately species included in the studies we reviewed, the ten most studied species were trees.

How to Obtain Superior Quality Control for Seed Testing	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.

Blogs News Seed Sourcing Grant: Addressing The Need For Quality Tree Seed The Seed Sourcing Grant has opened for a third round in England. By Megan Shirley · December 11, What came first, the tree or the seed? Above: Oxley Wood, Essex: Collecting dry seed in thinned area. Copyright: Clive Ellis 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. Forestry Reproductive Material definitions Forest Reproductive Material FRM refers to fruits, seeds, cones, cuttings, and planting stock used in forest establishment. Basic Material is the plant material from which FRM is derived and includes Seed Stands and Seed Orchards. Seed Stands and Orchards are managed by Forestry Commission through the Forest Reproductive Materials FRM regulations and voluntary scheme, which includes a National Register of Basic Material. Seed Stands are defined groups of trees in the landscape from which seed is collected. Seed Orchards are planted using seed or clonal material from known parents and are generally situated outside of the natural landscape in an area convenient for seed collectors. Above: Lime seeds Support For Tree of The Future 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. Any Questions? What are the benefits of registering a Seed Stand or Orchard? VisualV1 - Plus Created with Sketch. VisualV1 - Plus Copy Created with Sketch. The location and details are publicly available on the National Register of Basic Materials so all potential seed collectors are aware that they are available. Planting stock is traceable throughout the collection and production process to a registered source. The genetic quality and origin of the seed is known and validated by inspection, except for Source-Identified, unknown origin stands where an inspection is not required. Having more Seed Stands and Orchards across more seed zones increases genetic diversity and more resilience to pests and diseases and climate change. It also provides greater resilience of seed supply in case production fails in one area due to weather conditions. What is the minimum number of trees required for a Seed Stand? Can trees still be thinned or selectively felled from a registered Seed Stand or does it have to be left alone once registered? How do I find seed collectors to visit my Seed Stand or Orchard? Once a stand or orchard is registered, can anyone come onto the land to collect seed? Do seed collections conflict with managing a woodland for biodiversity and natural regeneration?
