Stages

Go back to Tree preservation orders summary

These are the questions we answer during the Research stage.

Answering them wil help us learn more about the Tree preservation orders consideration, determine if a data standard is required and whether we know enough to move on to the next stage.

  • Do we understand the lifecycle of a Tree preservation orders?

    Yes

    • Document a stage of the high-level lifecycle of a Tree preservation orders

        description
        There is legislation on the revocation of a tree preservation order, under regulation 11, which states that: Where an authority revoke an order they shall— (a) endorse the original order with a statement to the effect that the order has been revoked, specifying the date of the revocation; (b) notify the persons interested in the land affected by the order that the order has been revoked; and (c) withdraw from public inspection the copy of the original order made available in accordance with regulation 5.

  • Do we understand how the data is created/produced?

    Making and confirming a tree preservation order - Flowchart

    In regards to the creation of data (for those LPAs that already have polygon data), this remains unknown. For “tree” and “tree-preservation-zone,” we expect that the OS basemap will be used as a guide, but will likely not be traced to produce the data. “Tree-preservation-order” is the dataset pertaining to the official documentation of the TPO itself, and so being owned by the LPA will mean there is no input from a third party in the creation of this part of the dataset.

  • Where will or should the data be used?

    The presence of tree preservation orders will influence the amount of prospective development and will impact the amount of information and research required to fully complete an application.

    • Conservation Areas - There is a link between Trees and Conservation Areas in the legislation.
    • Local plans - TPOs are occasionally referenced in local plans, so we think that this consideration feeds into the process of creating a local plan.

  • Who are the statutory consultees for Tree preservation orders?

  • Other than the statutory consultees who are the primary users of Tree preservation orders? How do we expect them to use Tree preservation orders?

  • What are the planning needs for this data?

  • Who are the types of users who might benefit from having access to Tree preservation orders data?

  • What are some potential uses of Tree preservation orders data?

  • What's the value of adding Tree preservation orders data to the platform?

  • From what we have learnt so far are there any risks to making Tree preservation orders data available?

    • Licensing - currently, available data is not always clearly published under an open licence
    • Digital Immaturity - Local planning authorities (where data is not currently available online) may struggle to find the capacity to create polygon data for tree preservation zones and point data for tree preservation orders
