SPB Spot Growth Animation
3D visualizations of southern pine beetle (SPB) infestation spot growth can help us understand the process of predictive trends of spot growth, and provide an organized spatial visualization technique to evaluate effects from different silvicultural treatments.
- In these visualizations, researchers used five different tree foliage images to represent the stages of SPB attack:
- green foliage represents live and unaffected trees,
- light green foliage represents the fresh attacking stage,
- fading trees represent the stage of fresh attacking to developing beetle broods,
- red foliage represents the stage of developing beetle broods, and
- grey foliage represents dead trees without live beetle broods. -

SPB Spot Growth - High Density Stand- Through this vivid animation, we can clearly figure out the trend of SPB spot growth and the shifting pattern of different attacking stages.
- SPB Spot Growth - Medium Density Stand
In the medium density stand, the SPB spot expanding speed is not as fast as the stand with high density. - SPB Spot Growth - Low Density Stand
Comparing with the high and medium density stands, the pattern of SPB spot growth in the low density stand is significantly sparser and slower. But the affected areas in the lowest density stand would not necessarily be the smallest among different density stands. - SPB Spot Growth - Mixed Species Hardwood Stand
In this visualization, researchers used another tree foliage color to represent the hardwood species to distinguish from the pine species. This gives a clear and realistic representation for identifying different species and showing the different pattern of SPB spot growth between a pure pine stand and a mixed species stand. - SPB Spot Growth - Young Pine Stand
Comparing with mature pine stands, the trend of SPB spot growth in the young pine stand is obviously sparser and smaller.
