Grants and Funding Opportunities
Explore and pursue funding sources to support your arboretum’s growth.
Tree and woody plant collections are the heart of every arboretum. Tree collections require thoughtful planning, expert care, and ongoing documentation.
Grant funding can serve as a transformative tool for arboreta of all sizes. Funding can enable institutions to grow their collections, expand programming, and deepen their conservation impact.
Whether you’re a newly established arboretum or a long-standing public garden, external funding helps bridge the gap between vision and capacity, fueling high-impact projects that might not be possible through operating budgets alone.
When exploring potential grants and preparing to apply for grant funding, read ArbNet’s Tips to Apply for a Grant to ensure your organization is set up for success.

Tips to Apply for a Grant
Grant funding is competitive. Many agencies provide tips on completing applications. Be sure to read those when applying. The general tips below will help you write a successful grant.
General Tips
- Read the entire grant application guide and follow instructions carefully.
- Application requirements vary across programs and industries, so look closely at the notice of funding opportunity for each specific grant program to ensure that you are addressing all the requirements and criteria for the grant program in question.
- Pay close attention to the scoring criteria and address each of those criteria to the best of your ability.
- Be sure to include any additional forms or attachments that are required.
- Pay attention to deadlines—these are usually inflexible, and if you submit your application past the deadline date, it will not be considered.
- When writing your proposal, be clear and concise, establish your major points, and avoid unnecessary complexity. These points are the primary items on which the application will be evaluated.
- If provided, use the samples and checklists included in the application.
- Separate fact from opinion.
Sections of a Grant Application
Grant applications are typically composed of several sections, as outlined below. Know what information you need to include for each section.
Project Introduction
This section is similar to an abstract. The Project Introduction is often written after most, if not all, of the proposal is completed.
The Project Introduction should clearly explain what you are using funds for, and should be written in a way so that any reader can understand quickly and clearly what the project will deliver.
Project Justification
In this section, define and explain the problem that your project will attempt to address.
Some questions to answer:
- Why is it critical to address the problem now?
- What plans, studies, and data are available to identify or quantify the need?
- How will the defined population be impacted or different when the project is completed?
- What documented proof/evidence is available to support the need for your project?
- Who will your project serve?
- Are there any special circumstances to consider about your defined area/population?
- What are your organization’s needs?
Project Objectives
The objectives of your project should mirror what you are using the grant funds for in your project.
Note, there is a difference between goals and objectives. Goals are not measurable, whereas objectives are measurable. Objectives are performance-related, so make sure your project objectives are realistic. The objectives will become the criteria by which your project is evaluated if you are selected for funding.
Project Timeline or Schedule
The Project Timeline or Schedule should be detailed and clear enough that it can give the reviewer a general understanding of what the project involves.
In this section, you should discuss:
- How the project will be managed by your organization
- How project services will be delivered
- Who will be in charge
Be sure to include:
- The planned start date
- Activity
- Responsible party
- Completion date
- Milestones
- Deliverables and products
You should only cover those steps and tasks that will be supported by grant funding.
Project Budget
- Costs and project elements must be well-defined. Explain what costs are associated with each element and what portion of the costs will be covered by each of the funding sources.
- Check the application directions or ask the grant coordinator to determine how the budget should be organized (usually in columnar form according to general accounting principles).
- Include all costs associated with capital and non-capital expenditures, and all assumed in-kind services, volunteer efforts, and indirect costs.
- Only include items covered by the grant funds. Do not include a miscellaneous or contingency category.
- Don’t forget that this project will take place in the future, so budget numbers should account for inflation at the time of expenditure.
- Like the project timeline, the project budget should provide enough detail that the reviewer can gain a general understanding of what the project entails.
Assemble a Grant Writing Team
This usually consists of:
- Senior-level management (who must support and sign grant applications)
- The project manager (who is the primary source of project-related information)
- A grant writer
- An editor (otherwise unaffiliated with the project so that they can provide an independent assessment of how well the application presents the required information)
- Finance expert(s) (to help develop a good budget)
