OTISS lets you divide an estate into several ‘sites‘.  A ‘site’ could be a park, a field, a groups of fields, a property, a car park – whatever you want it to be. The OTISS
site record includes;

• A general description of the site, including notes on access arrangements.
• Location/address information of the site and the access point.
• Contact information (name, telephone, email) for the site manager, caretaker, warden or key holder.

Sites are used as convenient ways to divide up and the trees and site furniture.

• On the OTISS Map and Spreadsheet web pages, sites are used as a quick way of parts of the viewing the estate.
• Surveys are always carried out on a per-site basis.
• Reports can be created for a specified site or for all the sites together.

Tree Safety Zones

Sites can also be used as ‘risk zones‘ as part of your Tree Safety Policy. Site and zones are the same.

A site/zone is allocated a Risk Category of high, medium or low. The high risk category is recommended for ‘where there is frequent public access to trees‘ (e.g. in and around picnic areas, schools, children’s playgrounds, popular foot paths, car parks, or at the side of busy roads) – see OTISS and HSE guidelines

Note on Performance.

Although there is no limit to the number of trees/items within each site, for performance reasons on the website and on the mobile survey devices or phones, it is best to restrict each site to less than 400 trees.
