admtools vs forestTIME: at a glance
What is admtools?
The age-depth engine under a small stratigraphy stack, growing one adapter at a time
admtools estimates and manipulates age-depth models, with the generics time_to_strat() and strat_to_time() as the transformation layer a small stratigraphy stack is built on. Since 0.1.0 it has accumulated the S3 vocabulary that work needs — sac for sediment accumulation curves, timelist and stratlist for time- and height-associated data — and then adapters outward: pre_paleoTS for StratPal and paleoTS in 0.4.0, FossilSim taxonomy and fossils objects in 0.5.0, and age-to-time transformation for FossilSim in 0.6.0. Version 0.5.0 also added what it calls basic functionality for depth-depth models alongside the age-depth ones.
What is forestTIME?
A forest-inventory pipeline grew the strata machinery it needs to make population estimates.
forestTIME turns US Forest Inventory and Analysis data into annualized carbon and biomass estimates by interpolating between the years each plot is actually measured. Version 2.2.0 adds fia_assign_strata(), which matches every plot-year to an EVALID, estimation unit and stratum along with the values needed for population-level estimation with variance. The composite ID scheme also changed order, which breaks joins written against the old one.

The age-depth engine under a small stratigraphy stack, growing one adapter at a time
◆ Current state
admtools estimates and manipulates age-depth models, with the generics time_to_strat() and strat_to_time() as the transformation layer a small stratigraphy stack is built on. Since 0.1.0 it has accumulated the S3 vocabulary that work needs — sac for sediment accumulation curves, timelist and stratlist for time- and height-associated data — and then adapters outward: pre_paleoTS for StratPal and paleoTS in 0.4.0, FossilSim taxonomy and fossils objects in 0.5.0, and age-to-time transformation for FossilSim in 0.6.0. Version 0.5.0 also added what it calls basic functionality for depth-depth models alongside the age-depth ones.
◆ Where it's heading
This package moves in step with StratPal, from the same group: admtools 0.4.0 shipped its pre_paleoTS transformations fifty-seven minutes before StratPal released the class itself, and both took on FossilSim within a month of each other in spring 2025. The pattern is consistent — establish generics, define classes, then connect to whatever package the field already uses. The depth-depth work is the one thread pointing inward rather than outward, and it is still described as basic.
◆ Prediction
Depth-depth models are the obvious thing to finish, since they mirror age-depth machinery the package already has; expect any release here to be shadowed by a matching change in StratPal within weeks either side.
forestTIME
0.0INFRA · APIS
A forest-inventory pipeline grew the strata machinery it needs to make population estimates.
◆ Current state
forestTIME turns US Forest Inventory and Analysis data into annualized carbon and biomass estimates by interpolating between the years each plot is actually measured. Version 2.2.0 adds fia_assign_strata(), which matches every plot-year to an EVALID, estimation unit and stratum along with the values needed for population-level estimation with variance. The composite ID scheme also changed order, which breaks joins written against the old one.
◆ Where it's heading
The arc runs from a duckDB-backed script to a package with a design-based estimation story. First the database layer was removed in favour of a single interpolated table; then the function surface was consolidated behind fia_ names and fia_annualize(); then expansion factors appeared; now the stratification the FIA estimators actually require. Each step moves closer to producing estimates users can put an error bar on rather than interpolated numbers.
◆ Prediction
The notes name a temporary workaround for woodland species, whose carbon and biomass code is missing, and say fia_estimate() will eventually handle them directly. That, plus variance calculation built on the new strata columns, is the visible next work.
