modelling trees/bushes with daisy

[Maria Eliza Turek]

Dear DAISYcommunity, 

I am working on a project where we need to simulate small trees/bushes with DAISY. I saw in the model library the existence of a "vegetation.dai" file, but that would not suit our needs, since we simulate the early stages of development of the bushes, until they are removed to be used as ornamental plants. There is a paper that uses DAISY for simulating afforestation (reference below). I believe the setup would suit, but I could not find auxiliary files for it. Does anybody have experience with this and could share the input files? 

Thank you very much,

Maria Eliza

Dear Maria Eliza

 

Thanks for reaching out. It sounds interesting. What type of outputs are you interested in simulating?

 

Daisy has two options for simulating trees/bushes “permanent” and “afforestation”. You can read more about these in the Technical Description, Chapter_10.pdf.

The “afforestation” option has never been tested and should therefore be calibrated and tested against data before use.  

 

The paper you mention uses the permanent option to simulate forest stands of different ages.

 

The most recent use (that I know of) of Daisy to simulate trees are the work by Manevski et al., 2019 and 2024 (see full reference below), where they also apply the permanent option to describe the effect of poplar trees and willow, respectively. Both only using the water balance calculated by Daisy and combining theses with measurements of the soil nitrate concentrations to estimate nitrate leaching.

 

Kind Regards,

Maja
