arbour

Create a mini-application called 'Arborist' using the Python package 'arbour'. This application will serve as a tool for urban forestry managers to efficiently manage tree inventories within a city. Arborist should include the following functionalities:

1. **Tree Inventory Management**: Users should be able to add new trees to the inventory, update existing entries, and delete trees from the database. Each tree entry should contain details such as species, location (latitude and longitude), age, height, circumference, and health status.

2. **Health Assessment Tool**: Utilize the 'arbour' package's core features to assess the health of each tree based on its recorded data. The assessment should provide a score indicating the overall health of the tree, which can help in prioritizing maintenance efforts.

3. **Geospatial Visualization**: Implement a feature that visualizes all trees on a map using their geographical coordinates. This map should allow users to zoom in/out and pan around different areas of the city. Clicking on a tree marker should display its key information.

4. **Report Generation**: Develop a report generation module that creates detailed reports about the current state of the city's tree population. Reports should include statistics such as average tree age, most common species, and overall health score distribution.

5. **User Authentication**: Ensure that only authorized personnel can access and modify the tree inventory. Implement basic user authentication using tokens or session-based authentication.

The 'arbour' package plays a crucial role in the health assessment tool by providing algorithms and models specifically designed for evaluating tree health. It processes the input data (age, height, circumference, etc.) and returns a health score for each tree, which is then used in the inventory management and reporting modules. Additionally, explore if 'arbour' offers any geospatial analysis capabilities that could enhance the visualization and reporting functionalities.
